Proving Young's Double Slit Interference Equation - IB Physics

I give a derivation of Young's double slit formula. The double slit formula is used to find the pattern that the interference of two light waves create when they pass through double slits in a diffraction grating.

Young's double slit formula connects the distance between two slits in a diffraction grating, the distance from the diffraction grating to the wall, the distance between points of maximum constructive interference, and the wavelength of light.

your videos are the most concise and understandable physics tutorials I've ever seen, your channel deserves so much more attention😭😭

[santi]

oh my god literally the best explanation on youtube. thanks mate

[Pairlesspearl]

Oh I just love with this explanation..Your videos are just wow...!Seriously saying..the best explanation ever..! Is there anyone like me seeing it in 2024.?

[sajidmahmudchoudhury]

The way you explain each topic, that's amazing! Your videos help me a lot as a Facilitator. Keep up the good work brother!

My IB physics teacher couldn't prove this equation 😅, now I understand it completely. Thanks a lot!

[johnpoo]

Amazingly explained, makes so much more sense now

[bikrambiswas]

Thank u too much..I am too much happy with ur explaination ..

[Lee-sgmu]

Awesome! Thank you for your great lecture!

The video recorder and the light source are using the same electricity power source probably.

Thus the light source and recorder are sharing a same informationcommunication channel (the electricity source).

Try to use a charged battery powered recorder, this cuts off the information communication channel between the light source and video recorder.

Better still, if the light source are also using its own charged self powered different battery source.

Thanks a lot, saved my live, double slit was about to kill me

For the double slit diffraction equation at the end, the IB formula booklet doesn't include the constant 'n', but yours does. Could you please clarify that? Thanks

[hasan]

Why cant we use this equation for diffraction gratings ??

[thegameguy]

what programm did you use to make these videos?

It was an informative lecture but just lost me at the end when the angles came, I did not get the proper concept or reasons for them. I hope someone could explain in little detail or maybe you could make a video on it again.
