c = \frac{1}{\sqrt{\mu _0 \epsilon_0}}

v = \frac{c}{\sqrt{\mu _r \epsilon_r}}

I = \frac{1}{2} \sqrt{\frac{\epsilon_0 \epsilon_r}{\mu_0 \mu_r}} E_0^2 \,\,\,\,\\,\,\,\,\ B_z = \frac{E_y}{v}

I_{tot} = I_1 + I_2 + 2\sqrt{I_1I_2} <\cos \delta >

where

\delta

is the relative phase between the waves.

n \equiv \frac{c}{v} = \sqrt{\mu_r \epsilon_r}

\frac{\sin\alpha_1}{\sin\alpha_2} = \frac{\lambda_1}{\lambda_2} = \frac{v_1}{v_2} = \frac{n_2}{n_1}

\alpha_g = \arcsin \left( \frac{n_2}{n_1} \right)

\sin\left( \frac{A + \delta}{2} \right) = n\cdot\sin \left(\frac{A}{2} \right)

Where

A

is the prisms top angle and

\delta

the reflection angle.

N.A. \equiv n_0 \sin \theta_m

N.A. = \sqrt{n_1^2 - n_2^2}
