An EM wave has wavelength $\lambda=500\,nm$ in vacuum (green light). Find frequency, wave number $k$, angular frequency $\omega$, and amplitude $B_0$ given $E_0=50\,V/m$.

A light ray travels from water ($n_1=1.33$) to air ($n_2=1.00$) at incidence angle $\theta_i=30°$. Find the refracted angle and the critical angle for the water-air interface.
