Dear Grant, got this explained today in uni, a bit unclear at some point, but this visualization and brings up amazing intuition, tysm.

It is unfair this man has such amazing animation skills AND explanation skills

Is there a measurement that shows the effect of the generated light wave in front of medium? Is this the reflection?

wait but in ur diagram, the electron waves propagate both ways so why doesn’t it affect the wave before it comes in?

As much as I like the more sciency explanation I feel the phenomenon could be easily explained by thinking about how moving through water is slower-

what if light dont pass thru but reflect, like when we see it, does this work the same?

how do I study mathematical proofs? 😭

Is there a mathematical proof of the ”kickback” theorem?

if phase kick from additional layers is additive, wouldn't that mean the wave velocity within the medium is not constant?

This is the clearest explanation of this effect I’ve seen

Is the light, therefore, actually a different color while in the media?

I don't really grasp why it gets shorter just from kickback. Shouldn't it just get shifted back a bit?

this is also the cause of reflections. the induced wave propagated back out of the medium and is the reflection

if it's the interaction of two waves, does the original exit the glass the same as it entered or modified?

I really appreciate this explanation, but my brain seems limited
