Wave Theory of Light

(1) c = λ v

(2) Wave number: $1/λ = v/c$

(3) $_1 μ_2 = {μ_1}/{μ_2} = {sin i}/{sin r}$

(4) $_1 μ_2 = {c_1}/{c_2}$

(5) $_1 μ_2 = {λ_1}/{λ_2}$

(6) $μ_g = {v_a}/{v_g} = {λ_a}/{λ_g}$

(7) $μ = tan i_p$ $i_p$ -> polarizing angle

(8) ${cos i}/{cos r} = {\text"width of beam in air (medium 1)"}/{\text"width of beam in dense medium (medium 2)"}$

(9) $i_c = sin^{-1} (1/μ)$ $i_c$ -> critical angle

(10) Doppler effect: $f = f_o (1 + {v_r}/{c})$
$v_r$ is towards observer

-$v_r$ is away from observer
