A beam of light is incident from the air on the surface of a liquid. If the angle of incidence is 30.0° and the angle of refraction is 22.0°, find
a) the index of refraction in the liquid
b) the speed of light in the liquid
c) the wavelength and frequency in the liquid of a beam of light that is seen to have a wavelength of 562 nm in air
d) the total internal reflection critical angle for a beam originating in the liquid when surrounded by air.
