How can I prove that $T_\pi = 0$ at Brewster's angle? [closed]
So, I've been trying to prove this with pure trigonometry just for fun, without using the fact that $R + T = 1$, but no success. Here's my last try, using a combination of both facts that the angles ...

How to understand the Fresnel relation $1+R=T$? [closed]
From the perspective of energy conservation, we are familiar with the relation $T+R=1$ (Set the incident wave amplitude as 1, $T$ and $R$ are Fresnel transmission and reflection coefficient, supposing ...

Can refractive index be used interchangeably with wave impedance?
Everything I've been taught so far for EMR and waves at an incidence has been using the refractive index.
for example, the reflection coefficient for a wave normal to an incident is
$$R = ((n1-n2)/(...

Difference between scattering and refraction?
I while back I learnt that when light is incident on a dipole the dipole will scatter the light, and when it is incident on a material of a different refractive index then the light refracts. From the ...

optical diffusion (scattering) versus refraction
When an electromagnetic wave meets an interface a part of it is reflected and part of it is refracted (and from the refractive index I can calculate the angles of propagation and the intensities using ...
