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?
Answered by Neoh
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.
