Exercise 1EM wavesMedium
📋 Problem to solve
An EM wave has wavelength λ=500 nm\lambda=500\,nm in vacuum (green light). Find frequency, wave number kk, angular frequency ω\omega, and amplitude B0B_0 given E0=50 V/mE_0=50\,V/m.
Exercise 2RefractionHard
📋 Problem to solve
A light ray travels from water (n1=1.33n_1=1.33) to air (n2=1.00n_2=1.00) at incidence angle θi=30°\theta_i=30°. Find the refracted angle and the critical angle for the water-air interface.
