6:17 the equation for the effective refractive index only works with extraordinary rays. 9:03 The horizontal rays should be slower. I drew the outgoing arrows the opposite way.

This video was by far the clearest and best explanation of how birefringence interacts with light I've seen so far! I really needed this. Thank you so much for this content!

@@ReumiChannel Would you be able to answer how the refractive index of a medium affects the path length? I am studying a case where a Fabry Perot resonator is made using a birefringent material. So I was analyzing the FSR along parallel and perpendicular polarizations

@@AnujDineshTripathi Hmm.. polarization dependence of a Fabry Perot? I'm not sure, but since birefringent materials have n_e and n_o separately, it should affect the path length (The angle of refraction, and the speed in the material would definitely be slightly different). By the way, it's quite difficult to calculate the angle of refraction when a ray is entering the birefringent material slightly angled (so incident angle isn't zero). That's like graduate level. That's all I could tell you.

hi, I have a cuestrion, it is trure that when a birrefrigant cystal is radiated with ligth at a 45º angle to its optic plane, the ligth that was originaly in fase will end up out of fase, becouse it does not take the sema time to go through the x axis ande the y axis. However, why is this not in opposition to the principle of least time??

Good question. You should first ask what group velocity is. Also, see graphical explanation for Snell's law.

I don’t understand. Why are there two n0?
@d3s4ster
4 ай бұрын
Because in a uniaxial crystal (where you have three n: n1, n2 and n3), you have two n that are equal to each other, so here for example it is n1=n2 and n3 is different. And then you rename it to no (not zero, but 'o' which stands for ordinary) and ee (where the 'e' stands for extraordinary). In result, we have "two" no because n1=n1=no.
