That was the best explanation of the double slit yet. Thank you!

Thankyou. Please do share.

Absolutely one of the clearest explanations I have heard on a complicated idea. Use of the two strands of wavelengths was magnificent. I can now use the slit distance idea to see how the the method can be used to measure particle size.

It was really helpful in visualizing the experiment which perhaps in this case is even more difficult than the mathematical calculations involved

Why d must be smaller then L?

Hi Paul. It is an excellent video. Especially for those people, who have been hooked up by physics. The opportunity to touch the science by bare hands. Thumbs up!

Excellent video, been trying to learn this concept for a few weeks, but this finally made it sink in.

im not sure if i have done something wrong but the calculation at 16:58 may be incorrect, a micrometre is x10^-6 therefore using 3 rather than 300, you would use 3x10^-4. using this, the answer from a calculator is 5.54x10^-7

This is a great explanation of the double slit experiment. I'm ashamed to admit i am a college sophomore taking physics 2 in the usa and couldn't visualize this and nothing the textbook or my professor provided helped with the conceptual part of this. Thanks!

The experience of non-physicists with physics is typically distressing. You are not alone with that experience. I remember having an engineering student come to me about a physics problem. He was totally desperate because the teaching materials used in those classes for engineers were totally insufficient. What a physicist will (have to) do if they don't understand the classroom materials is to go into the library and look for textbooks that explains the material in a way that helps him or her to overcome the mental block. That takes an enormous amount of time. I remember spending endless hours in the library trying to get up to speed with some of the material. Students of other faculties who are only taking physics because they have to usually don't have the time to do that.

For the 300 micrometer separated slits, what is the open space distance of the slits themselves? The reason I ask is that the wavelength of your red laser light is 623nm and I am curious about the relationship of the slit size (not just the distance between the slits) and the size of the wavelength passing through the slit.

One door is direct current and a alternate door is alternating current. Eyes nostrils ears are all two doors. It can also be described as seeing a rainbow from a different perspective. Particles should be looked at as people and many things will make sense

Instead of a “wave” could it be light (heat, energy, protons) traveling in every direction from the beam?

Yes it could be

Hii, I have a doubt. In video it was demonstrated that using RGB light we get a rainbow effect. However I believe since wavelength of Violet is less than blue. it wont be possible to see any violet color. Plz advice. Thanks.

@PhysicsHigh 4 жыл бұрын

That’s a good point, a small flaw in my explanation. Then intent was to say white light. But you are correct, you would not see violet if I strictly used RG and B light. Thanks

We had a problem with our calculation (see 17:08 in the video). You used 3.0x10^-7, but if it is 300 micrometers shouldn't it be 3.0x10^-4? We also end up with 5.54x10^-7, rather than 5.56x10^-7. Why does this happen??

So a single slit of the required profile causes diffraction at both opposing edges and these diverging emissions cause the constructive / destructive interference which is observed as the wave like lines on the observation surface? And if so, this means the obstruction with the double slits would cause the same destructive / constructive interference pattern emission form each slit, which then interact with each other and the constructive / destructive Interference pattern with each other? This should be able to be proven if so by showing the double slit causes a pattern which is explainable by the interference of two emissions of interference light waves, and not the interference of two emissions of non-interference light waves....? If you know what I'm trying to convey?

When you are shining your laser beam at the White paper, isn’t light traveling from the beam of light in every possible direction? If the room was dark wouldn’t you see the laser beam? And since you can see the beam that means light from the beam has reached your eyes? So, the beam is traveling with the majority of its photons in a straight line. But some photons are also traveling in every other direction possible. Once this beam reaches a slit, the photons traveling perpendicular to the beam has to squeeze through the slit. And once through the slit light from the beam again travels in every direction possible. Which causes it to interfere with itself.
