a ray of light (f = 5.09 x 10^14 Hz) traveling in air strikes a block of sodium chloride at an angle of incidence of 30 degrees. What is the angle of refraction for the light ray in the sodium chloride?

3 answers

Google the refractive index of sodium chloride. Let the value be n. Then solve with the simple

n = sin i/sin r

The given frequency of speed of light in air is not useful.
