Finally, I was struggling to understand Wave Optics a lot until this video. Amazing, really amazing animation. If it was possible, I would've liked you to also dive into the mathematical aspects of it such as why the first dark fringe would appear when the path difference is equal to the wavelength and how it differs from YDSE and such. Still, I was finally able to understand the phenomena and I can take it from here. Thank you so much.

[@ZoeTheCat]

Eugene: I really liked the phasor technique when the slit (d) becomes appreciably larger than lambda. I hadn't seen that before. A few questions about that: 1) This reduces to the standard Young Experiment when d>Lambda, does it make any sense to use a sub-source separation smaller than lambda? 4) What does a negative phasor magnitude imply (Partial trough?) 5) Are these techniques more applicable for fluid-waves rather than light-waves of single color? On a more important note, I presume these techniques are only an approximation to QED? As you know, QED produces ("amplitudes"--->probabilities at the back plane). I grapple with how simple phasor techniques which don't include quantum effects could match the mathematical Sum-over-history/Renormalization of QED. Thanks again for your beautiful vids.

wow! this video is so helpful to my understanding of diffraction and interference. i have an excellent optics professor but lecture-style learning is inherently limited. sometimes you just have to sit back, get stoned and watch these mathematical concepts visually and graphically.

[@rustybolts8953]

By far the best illustrated and explained series of lectures I've seen on the subject. There are some very odd experiments I have seen not very well illustrated but quite well explained; in which clever attempts where made to trick electrons into taking the wrong path. All attempts failed. The only explanation was that somehow the electron 'knows' ahead of time whither or not a barrier will be there thus always following the shortest path in the now. This left me scratching my head for years! It would be a challenge but I'm wondering if Eugene could produce a video addressing this phenomenality?

[@pendalink]

Amazing video! I really love how you're building off and combining old topics you already covered. One thing though, at around 12:38, doesn't that green line passing into the negatives on the x-axis suggest a negative amplitude, or is the only significant thing the actual length of the line? And if so, is there anything significant about the last point passing into the negatives? Thanks

[@EugeneKhutoryansky]

+pendalink, it is only the length of the green line that signifies the amplitude of the sum of the waves. The fact that its X coordinate is negative doesn't matter, since the green line is going to rotate around the theta axis as theta increases, and I was just showing the cross section for when theta is zero. And thanks for the compliment about my video.

Woah , sine function had a 3rd axis ? I don't understand , why the sin function have depth ? What is sine function in first place ?

[@456dave7]

The vertical axis, coming out perpendicularly to the x-y grid, is the argument of sine, say θ. This helix that wraps around this axis looks like a sine function of x vs θ if you look at it from the side and ignore the y-axis (as he did in the video). Likewise, if you were to look at it from a side where the x-axis is into the screen, i.e. y vs θ, you would get a cosine function. The reason this works is because of complex numbers: the green helix he plots is the function e^iθ, where i is the imaginary unit. Euler's formula states that e^iθ = cos(θ) + isin(θ). cos(θ) is the real part of e^iθ and sin(θ) is the imaginary part of e^iθ (because it is multiplied by i). So in effect the function e^iθ maps θ to two functions: sin(θ) and cos(θ), and you can denote each of them on a separate axis (so one axis for θ, one for sin(θ), and one for cos(θ)). If you look at only one part of e^iθ (the green function he plots) it's as if you only look at sin(θ) or cos(θ), depending on what side you look from.
