Just you wait and see what I have planned for the coming weeks. I'm going to blow you away with how much is about to be added! - changing channel name to OSC and then uploading a few hundred new videos, covering the new Math AI SL course, Math AA SL course, and Physics SL/HL.
I did the IB in the M19 batch, but I just came to say I remember watching these videos when taking physics HL, they helped a lot. Thanks for the resources!
Hello sir, why is there no single-slit envelope overlayed on the double slit intensity-displacement graph? I thought for n number of slits, there is always a single-slit envelope overlayed? Great videos btw!
It all depends on the situation - you can have them where there is the single slit envelope dominating, but then you have the double slit effect also happening (lots of alternating max and min), but other times for example if you have many slits, the single slit effect is negligeable and it's the multiple slit effects that dominate.
Hey, I am a bit confused as for the difference between S and Lambda. As in the graph when you show two fringes, they are basically two peaks, and the distance between peaks is wavelength.
The distance between the peaks is not the wavelength in this case. The pattern that appears on the screen may have a sinusoidal shape when we look at its intensity, but it is not a wave itself, so s does not measure a wavelength. The waves are the beams of light coming from each slit traveling towards the screen. The bright fringes are where waves interfere constructively, and the dark fringes are where they interfere destructively. So lambda is the wavelength of the light, and s is the distance between successive fringes (which is partially determined by lambda).
When I recorded, the video of me was indeed there, but when I saved it, for some reason it was all corrupted and unusable. :( You don't have to look at my dumb face for one video at least! :)
Good question! "s" is the fringe separation, "D" is the distance between the grating and the screen, and "d" is the distance between slights. We use lambda to denote the wavelength. Cheers, Mitch

We need more of these vids, they are really helpful as compared to online classes

Great to hear!
HI!!! You’re uploading after a long long time
8:49
There is a mistake I think, you said that 0.015445m becomes 0.15m but that isn't right
You're absolutely correct, thank you! I'll reupload as soon as I can. In the mean time, I'll make the change in the video description and title
where was this 2 days ago when I had my physics mock....
It was really helpful, thank you
I do agree so
I agree! It was pretty helpful:D
thank you
It was perfectly splendid.
I'm so glad it was helpful! Cheers, Mitch
thanks for posting this! does this playlist fill the entire corriculum of 2021 as well?
I'm updating all my playlists now, but yes, it will
8:12 it should be s=0.015m = 1.5cm = 15mm, there's a small mistake
Thanks, I had changed the title of the video with that.
7:38 isn’t it supposed to be 0.25 x 10^-3 not 10^-4? i think you wrote it wrong in the calculator
he wrote 2.5 x 10^-4 in the calculator which is the same as 0.25 x 10^-3
really good stuff
Thanks!
Hello sir, why is there no single-slit envelope overlayed on the double slit intensity-displacement graph? I thought for n number of slits, there is always a single-slit envelope overlayed?
Great videos btw!
This helped thanks g
Also, why are they the same intensity? I thought that intensity drops off significantly after the central maxima of m=0?
It all depends on the situation - you can have them where there is the single slit envelope dominating, but then you have the double slit effect also happening (lots of alternating max and min), but other times for example if you have many slits, the single slit effect is negligeable and it's the multiple slit effects that dominate.

Nooo, where's the cam
When I recorded, the video of me was indeed there, but when I saved it, for some reason it was all corrupted and unusable. :(

is s the wavelenght, what does fringe mean
Good question! "s" is the fringe separation, "D" is the distance between the grating and the screen, and "d" is the distance between slights. We use lambda to denote the wavelength. Cheers, Mitch
Thanks a lot(monthly tomorrow lol)
You're welcome! Good luck!
You mean double-slit diffraction. There is also single-slit diffraction.
