very cool video! i would not have expected the awesome results that you got. well done experiment! one minor thing is that a laser doesn't make a plane wave, they are typically gaussian waves which look like a spherical wave when you aren't close to the aperture. i hate coyotes too lol. keep up the awesome vids!!

"My shoes are 12 inchs long. Its very convenient." Cody, my man!

This is the coolest demonstration of this that I've seen. Really nice.

Photons are waves, except when they aren't.

Discovering this video in my subscriptions: "Coin As Lens?" Hmm? How? "Making an Aragoscope" What even is that? "Cod-" Oh it's Cody's Lab! Ok, I'll watch it.

I love Cody's Lab, and his yard, and his greenhouse, and his buttery kitchen, and his truck.

in phase >:)

This is the solution that Veritasium was looking for in his "is light a wave or a particle" video. Great that it worked for you! Edit: The name of the video is :"The brightest part of a shadow is in its middle" I highly recommend it!

That's crazy man, I hadn't heard of this until now. I LOVE SCIENCE!

_IN PHASE_

was half expecting a jump scare at the end!

Could you use the moon as the disc for a large space aragoscope?

I N F A Z E

Any sufficiently advanced technology is indistinguishable from magic.

if youtube takes this channel down im gonna boycott the f out of it

Cougars scare me more than wolves or bears or anything in the wilderness really. If a cougar wanted to kill you, you would most likely be mauled before you ever heard or saw it. I had one following me for almost a half mile through the woods before and never noticed it at all, and it was right behind me, like less than 50 feet. And I was hunting, trying to walk quietly and paying close attention to my surroundings. The only reason I know it was there is because there was snow on the ground and when I turned around to head back the way I came there were cougar tracks right on top of mine all over the place. Scared the crap outta me. I could just shoot some wolves or a bear, but you can't shoot a cougar if you're dead before you see it.

And then the thunderous voice from Heaven said... I-N P-H-A-S-E )))

This is so cool! Wish I had a camera to do this too. Thank you for this education, Cody!

As a electroptics student i must say this is simply the most impressive demonstration of light diffraction I've ever seen！No hard Maths involved, just plain old physics！

Was anyone else waiting for a jump scare at the end of the video? Great video as always, Cody! I had previously heard of this phenomena, but handn't seen it practically demonstrated. Impressive!

We need to get you some metric boots. :)

Holy shit that sensor is dirty. 😰😰😰

Beautiful demonstration, sir. Thanks for posting this video.

Such an addictive channel. I love science and not too bad at it but i wish school sciences where this interesting. Fascinating stuff explained really well and its got me hooked! Keep it up Cody!

Cody is going to make something so revolutionary that everyone will use it. I just know it.

Captain Cody is back at it again with things that shouldn't be possible but he's God so it is possible.

Nice job Cody! Many of my viewers pointed me to your channel - glad I found you!

Okay, so usually Cody's videos are about things I know at least something about and already kiiind of understand, but I really like to see applied practically. (Either that, or I cringe and hope he doesn't lose a finger, or worse). This was completely new to me and, other than the double slit experiment, even the basic theory is something I've never even read about. I love that. Thanks Cody. (Also, thanks for not endangering any digits in the making of this video).

I N P H A S E

When I was in class I'd often forget to bring my glasses, i was short sighted. It didn't take long for me to realise that when I squinted I saw slightly better. Being bored and blind in class I took this a step further and made a pinhole with my fingers, what I found was that If I made the right sized hole at the right sized distance I could miraculously read the whiteboard. I wonder if I was using this same principle

It's so awesome that all these channels I watch are so bonded, friendly and supportive to each other.

Thanks for doing what you do, very interesting to watch your videos.

Araragoscope Sorry, I stuttered

R.I.P Cody, I hope they find those Coyotes.

What I like about you and your videos are they're so down to earth.

Fascinating demonstration!

Hey everyone, cody's made a backup channel due to community guideline strikes. "Cody's lab backup" is the channel so go check out his update video!

HAH even Cody's feet are calibrated :D not in SI units though :/

had never heard this diffraction technique before.... thanks for teaching it to us... cool as always!

Cody...you are such an amazing person!

Cody, get a Sony A7s and use the extreme(but still usable) ISO of 409,600. You could have a must shorter shutter and measure way more light.

Cool video! Never heard of an Aragoscope..

Brilliant. Keep up the great work Cody, it's much appreciated.

man i can't believe how much I love your videos, you explain so well. Thanks!

Love the new intro cody!

"Focal lenght measurements"? I wish you told us that too! I mean i want to know how to do that measurements. The formula for that or the maths? Okay i seek more, like you say so. Really surprising this idea. Thanx!

I said to myself “how does that work, please teach me cody” when i saw the thumbnail. You’ve taught me more about science then ive learned in my entire highschool and college career so far.

You never fail to amaze me! great work!

can you make a schlieren camera? where you can see air current

Wow this is interesting. Something new for me that still is pure physics. This is really new knowledge for me, more insight! Nice, as always! And greetings from the netherlands (aka Holland)

7:55 that deep voice, nice video, I had never heard of it, quite surprising to be honest

You never cease to amaze and teach me something. Great stuff!

It would be possible to use the moon as the dark disk? How powerful would be such a telescope?

OMG! You're encouraging people to experiment with photons. I have to flag you!

This is my favorite KZfaq Channel. Thank you.

Absolutely amazing. I had never even heard of this before. Great work again cody.

"IN PHASE"

I've looked thru dozens of comments and seem to be the odd one out. Whenever you said "you can clearly see..." I couldn't. This is interesting because it seems to be the converse of a pinhole camera, which is a "wide angle lens". It's very easy to get clear fairly detailed images from that. Will you follow this up to get easily visible images from this, cos all I've seen here is a very low contrast blur which other commenters seem very impressed by and leave me thinking there must be something wrong with my eyesight?

Wow. PRIME QUALITY. So glad you (or the algorithm)brought this one back up. P.S. Thanks for the follow up resources. It allows BINGE second and third course consumption, before dessert. Thanks again.

You're an inspiration Cody. The literal and practical definition of the american dream. I love you.

I'll try my odds with a coyote than a cougar any day of the week. I had the privilege of being chased by a cougar about 8 years ago while I was at work on night in the TX panhandle

Hey everyone, cody made a backup channel due to community guideline strikes. "Cody's lab backup" is the channel so go check out his update video! this channel is facing being deleted and he cants even post a video to warn people!

Man you have a great mind and to also recommend other great utubers out there is being a great team player. I like your ideas

Great demonstration!

IN PHASE!

*converts 12 inches to 1 foot*

Great!! I am surprised that such a technique to magnify distant object exists. Awesome work!!

I would like to thank you cody, for inspiring us to study more science! Ever since i watched your video i enjoyed doing chemistry and electronic projects. I learned how to electroplate metals using copper acetate. I also learned alot of chemical processes which helps me with my lessons :) more power to you and your channel :)

Do more mining videos!

95% of this video is pure darkness. Cool.

Thanks for the demo!!

Nice video, and thx for the units in the corner it helps a lot to understand what you mean.

Cody is probably the only youtuber i still watch even if his videos quality is almost unwatchable.

I should be doing homework

I am properly amazed by the Aragoscope. I learnt something new today.

Excellent video there Cody, I didn't even know of this effect until I tuned in today, lovely work there man cant wait for your next post :). StAsh.

Do you get as much work out of that bulldozer as it gets out of you?

I really liked the timelaps at the end. Very interesting to learn that a come can be a very powerful lenses

That is the most incredible thing I think I have ever seen and I thought I had read up. Thank you. Pleased you are back online.

Wait... $1 coins do exist??

Nice intro

Mind blow. Well done sir

Damn awesome demonstration and equally as awesome to link more info!

Hi cody! Big fan, longtime subscriber. I REALLY want you to meet/collab with "styropyro" here on youtube. Make this happen! I've already said the same thing to him, and he was down to do it. DM/PM whatever you guys do on youtube. Make it happen! Best regards, sweden.

Bro, you got more than 4k a month on patreon, could you PLEASE get a better camera?

That is neat as hell! Another awesome vid from Cody! Thanks!

"Cougars, they don't scare me so much, because the don't hunt in packs." Badass! Also confirms the impression I've gotten about pack hunting from TierZoo (that it is OP).

Cody is the coolest guy on youtube.

Very nice demonstration

Always knew that light was a wave but had no idea you could do something like this with it. Great video man

And I thought this was going to be a "boring" beryllium lens for IR photography you continue to impress sir.

Man, this is really enlightening! Thanks a lot.

Your video made more sense and proved the concept better than the 2nd video in your description. you're kinda the diy youtuber of physics. experiments like these are great to try out yourself. just get the distances right and well i assume any coin would do the trick. I'd love to see a follow up video where you try to make some sort of gear where you can put the theory in concept . i can imagine it to be a difficult thing to make. just saying i believe you could :) if not i'd appreciate if you let me know why not. As footer just wanted to say i enjoyed your video's so much i really like physics but the school i went to didn't had the subject available(no teacher or enough students to fill a physics class). so this way i still learn why and how things work. hope you your channel keeps growing. best of wishes, Erin. P.s. : you inspire me allot, and i hope to learn many more things from your channel :D

wish i had a friend like cody, could just listen to him for hours going on about interesting phenomenon :D

your seamless editing skills never cease to amaze me! seriously though your goofy edits are far more entertaining than a bunch of jump cuts, keep up the good science dude!

Fascinating & wondering what a laser pointer would produce . Thanks again Cody and best wishes .

Shots fired by Cody! Great video

Thanks for converting distances, Cody.

Man this is super cool. It's crazy how some people still think reality is obvious and simple when simple things like this can baffle us That little moment after you said "ive seen what they do to deer" and then shuffled around, stood up, and sat back down was ominous lol, the look on your face was somewhat fearful. Yeah intelligence is a lot more useful when physically fighting a single opponent, you can pull some trick and win, but you can't really do much against a pack of predators unless you can physically overpower them or run away. Clever tricks aren't consistent enough to get you through multiple opponents in a row. And as humans, intelligence and endurance is basically all we have
