That should be standard equipment in every physics subject. Great setup.

If only we were taught Physics like this back in school 🤦

Bro casually thought my 12 grade physics in a shorts

I like how this is the perfect way to explain how light travels through a camera lens, and why precision in manufacturing them is so important!

Convex, concave. This is what glasses do to help you see better

I was so fascinated with lasers as a kid in the early 80s, but I never expected light to be so cool 😎

That multi laser tool looks really cool for testing resistances and various educational demonstrations like you did here

Damn this type stuff is what we needed when getting interested in photonics as a teenager. Sure would have saved a lot of time and made learning more efficient over the last fifteen or twenty years

A great way to describe and teach the features of a parabola’s vertex. It also means the derivative at that point is 0.

You're truly deserving to be famous

Nice demonstration, I worked with a optical laser table once for a research project I was doing. What surprised me the most is how perfectly and precisely you need everything lined up for literally anything to work.

Really cool demonstration! I would love to see something like being used to explain why pictures come out reversed (upside-down) and the sensor has to reverse it to make it more like what we humans expect

It's cool to watch the beams converging and diverging depending on the lens used. This could be useful in power transmission

Thats actually amazing, learn something new everyday

Always wondered why camera lenses had so many elements!

I love this demonstration. So easy to see what's going on with lasers as opposed to say a torch or bulb

This guy needs to be famous

idk why but watching lights bend is so entertaining

Thank you for showing optical geometry through experiments, it helps a lot for understanding !

Love this. Looks like the objectives / elements in a camera lens and is an excellent demonstration. Next do diffractive optics!

Love your focus, man. The future looks bright for you

"Laser ray box", a hell of a device.

Really shows how precise actually well done systems are

I love modern physics and science stuff. Thank you for sharing.

i’m blessed to have a physics teacher who actually teaches like this

bro really made a constant F number zoom lens

And there you have it: the derivative of the curve is zero, there is no slope in the curve of the lens, and the lens is essentially flat

Beautiful!

You could totally make a puzzle game out of this concept

This reminds me when I tried to use lenses on my first laser and was learning about rainbow vs single wavelength spreads.

This is basically the concept of derivatives in physical form. If you zoom in enough to any point on a curve, there is a tangent line that will match the line segment perfectly.

Really cool. Also you sound just like Lewis Hamilton, and that's great.

Concave lens and convex lens are fun to play around with

lovely seeing a physical representation, thank you!

This helped me understand how zoom+wide angle lens works! Thank you!!

Took an optics class where we went over stuff like this, and I did NOT pay enough attention., realizing over the years how optics are hugely important! Can’t wait to see more!

He's not fat, he's just big glassed 😂

That type of demonstration should be in every school at physics classes

I love this demonstration, I imagine camera lenses utilise this phenomenon a lot

Taking notes for scifi laser guns

Super dope! Love the science behind lasers and focusing lenses!

Excellent video. As a schoolboy this kind of thing fascinated me and it’s so good to see this kind of content promoted

Kinda looks like a awesome Spider-Man symbol when you had the last crystal on

So cool. The lines made me think of a creepy animal they found in the deep ocean though

That's pretty cool actually.

Fascinating, thanks for showing that !

Laser Chess 2 is lookin' good.

Actually quite interresting! Finaly a good short

The reason the lenses don't do anything in the middle has nothing to do with their depth or local curvature at a point. It is because the lenses you placed in the middle are reflectionally symmetrical. Since the focal point of the first lens falls exactly in the middle, the 2nd half of the middle lens undoes whatever refraction the first half of it did. If the lenses were geometrically perfect, the double convex lens should also affect no change.

This is dope not sure what I’ll ever do with this but nice to know

This can also be used to teach the differet errors of refraction in medicine.

Great effort and explanation! Thanks!!

Great... But if all light have different colours then it can be more impressive and understand of the light....

I'm an optometrist. That's the very reason why it's very important to position the center of lens to the center of the pupil because the "perfect" grade is at the center. The scattering of light you see is because of the prism since converging and diverging lens are made out of prisms. And prism causes discomfort for some patientd because it focuses the image in other direction.

We only learn it in theory but now actually seeing it makes alot easier to understand.

Lazer: hey hey glass Glass: what??? Lazer: Let's we lie to him Glass: ;) only legend can understand

Cool demonstration. I wish we would have had this in our school when I needed tot do a physics chapter about lenses.

Awsome setup and explaining 👏

Great demonstration!

With this setup here I had to do some experiments in school. Funny memories...

i wished my elementary school had this before making me do lens calculations

Cool cool *Writing down evil notes for my laser build*, nods.

That's really amazing!!

And that's how a cathode ray tube works with electron beams and coils.

This is pretty cool! 👍

Wow, this short might be the best bit of educational material to easily understand, what all the lenses in cameras do.

Actually, cremation doesn't really effect the bones, they have to go though a cremulater. So those bones going through Gideon...

And those combinations of lenses is how telescopes work

This looks so cool. Reminds me of portal 2

In calculus terms, the curve is differentiator and the center is = to 0

Thank you! I miss my childhood prism!

guy, is an interesting point of view, cause on book's draws show some about optics, but nobody tried show it with lasers, and they are lights that go straight ahead... when they were discovered (60's decade) were made in huges devices, and only in a scientist lab... time after, people thought on them like "star-wars" weapons... nowadays, to process information, but some dangerous on their management...

Brilliant. This what teaching should be like!! Bravo!!!

Completely extraordinary application of lenses and lasers I love it!

And this is how camera lens work Amazing

Aside from me actually understanding this. I wish, it came on my recommendations during final years of highschool

reminds me of expiraments we did in physics class... the curved glass, the lasers and all

Why is this so satisfying...?

ngl that's trippy

This is how work our eyes

omg I could play with that set up all day!

This is such a good demonstration

That can be used for Aberration correction.

This easily explains the topic of Convex and Concave lens. Nice video

That’s really neat. Thanks 👍🏻

The beauty of symmetry

i need only this type of video in my feed, thx

Nice to see :) would be nice to add where this would be used, if you happen to know as well

That’s a pretty neat setup

Cool demonstration!

I love practical learning...

Wish this video existed when I had Optics, makes everything much clearer Thanks for the video

this reminds me of the light tweezer expiriment (sorry if i spelt that wrong) it won the nobel prize in physics in 2018

i like these educational shorts

Bro I want dat laser ray box... I mean, I've always wanted something like that ever since I was a little baby boii... That's just so cool!

Cant wait for a 2$ company to cut footage fron this for their mobile game

I didn't know there was a laser setup for this. Now I need an entire video on it. Will check out your channel. Awhile ago I tried modifying a monoscope for use on a phone camera while reducing the vignetting around the edges, but it was very complicated trying to visualize it all. Now I wonder if there's an educational kit like this...

Ok but where is your secret laser super weapon?
