Apertures and Diffraction - Exploring Wave Motion (3/5)

[@TheRoxas13th]

This is what i called "clear explanation". Thanks!!

[@Nickpinn]

This video is excellent and has significantly improved my understanding of diffraction

[@MrMaxviwe]

+Nicholas Pinn you are black, so can I call u a nigga?

[@rajbal8894]

No words to describe, it's well described...

[@wsegal]

This is excellent. My class will really benefit from seeing this.

[@KashKumarlovekumar]

wow ! the lecture with experiment is a spectacular choice...

[@thepoptropicashow]

Is anyone else here the night before a wave function test?

[@Nichtzukennen]

No.

[@gibdopaminepls]

idk man, i'm in the tail end of an acid trip and this is riveting stuff, i gotta say.

[@ahmadeldesokey9844]

Very clean and clear explanation.

[@ActiveStorage]

thanks. People say that higher individual mass of the particle causes the wave to slow down. But the higher concentration of these particles causes the wave to speed up. Plus one has to account for "stiffness"(Shear_modulus) of the material and compressibility. The problem I see with "density" is it only tells us the amount of mass per volume. It doesn't tell us anything about distance between the molecules or how these molecules "interact" between each-other.

[@atrowell]

Excellent visualization. Thank you!

[@boofang10]

Brilliant and Simple 👍🏻👍🏻 .. tq Mr Norton 😁

[@mallikaarushi6277]

Brilliant demons for the concept

[@phoenixheart6]

In a more dense medium, the speed of the wave would be slower. This means that for the same frequency of a water wave, a mercury wave would have a shorter wavelength. This would mean less diffraction. Just remember that the wave speed is inversely proportional to the density of the medium.

[@Mulkek]

Thanks, and it's so clear & simple!

[@jacksonhuang8502]

thanks, mate .It helped me alot in understanding diffraction.

[@ifeanyichukwuidoko6599]

nice and brief explanation sir.

[@sabikunnahersumi6355]

Outstanding, thanks!

[@منيرةالعنزي-ج7و]

Nice experience ! Thanks

[@alizuhair4394]

amazing video!!

[@manethdulshan8978]

Thank you soo much 🙏🙏🙏❤️❤️❤️

[@rajatverma8644]

Thanks alot sir❣️

[@eiklin7074]

This is awesome !!! Thanks :D

[@alexandraforrai7390]

thanks! this really helps

[@busra1602]

Can someone explain why wavelength changes the amount of spreading? The wavelength and the width of the aperture are perpendicular to each other, so it seems like no matter what, the wave can pass through the aperture

[@fredrickjofrey3180]

Very clear

[@SS-ww2qd]

Lovely stuff!!

[@ActiveStorage]

does anyone know how diffraction would change if one uses mercury instead of water? or oil? or kerosine? Are there any formulas that can link diffraction with density of the medium? if any?

[@changw_w3040]

But, why does a shorter wavelength will produce smaller diffraction?

[@phoenixheart6]

That's true, I didn't know that higher concentration led greater wave speed. With the shear modulus though, that's only the case for a solid medium (I think, like a rope or something). I know physics, but not so much chemistry lol.

[@plusplus7272]

Thanks man

[@zainabdookhy2480]

Thanks

[@benwilms3942]

But why?

[@ardenkel1127]

These are not two factors. It's the same thing. The ratio of aperture width to the wavelength. If the ratio is small - lots of diffraction. If it is large - little diffraction.

[@xkriolox]

what happens when the wavelength is way bigger than the slit?

[@rutusayswhat]

Dário Mendes 1. When width of the slit = the wavelength of Light waves, hardly diffraction takes place. 2. When width of the slit > the wavelength of Light waves, no diffraction at all. 3. When width of the slit < the wavelength of Light waves, more clear-cut diffraction. Thank me later.

[@way2saturn]

nice

[@sasanidulmika1292]

super

[@JunerJourney]

Thanks I think it would better if this had sub since it's hard for me to listen

[@TheChangeYT]

it has now

[@PCP1992]

What I always struggled with was to find an analogy or metaphor to help me conceptually understand this phenomenon. I get the maths and the fourier transform and stuff... But conceptually understanding and visualising the fundamental principles which would lead to an experimental observation like this has been impossible.... Anyone got any ideas? Basically my question is: whyyyyy does this happen? Not explained mathematically please! I understand the maths!

[@omarshraim9856]

basically, water at the edge of the gap hits the edge and moves up and down, which sets off a series of circular ripples that will move away from the gap. (that's what happens to water in a ripple tank).

[@PCP1992]

@@omarshraim9856 Good try Omar, but now try to apply your explanation to Electromagnetic waves? Why do electromagnetic waves do the same thing?

[@ShauriePvs]

@@PCP1992 thank God I'm not the only one with this doubt, yeah analogies are always great for basic understanding but in reality water waves and EM waves are made very differently(like material And medium) but still the same diffraction phenomenon is occurring ... The question of how exactly...is still a mystery for me

[@joshuaharland6373]

Hello people from Physics.

[@Skippercarlos5]

hi

[@studentjohn]

This was good, nice a nd clear, not too wordy, used the demonstration aspect to good effect. May i suggest that the presenter insert just a tiny touch of humour, or a bit of information on howand why knowledge of diffraction is useful, to help the student engage emotionally with the subject?

[@davidhoward437]

This is description, not explanation.
