A ray of Red Light wave in air has a frequency of 4.2x10¹⁴ Hz. The incident light ray strikes the surface of a swimming pool (n=1.33) at an angle of 20 degrees. Some of the light is reflected and some of the light enters the pool.

At what angle does the reflected light rebound?
θ_reflection= degrees

At what angle does the reflected light refract?
θ_refraction= degrees
