A light ray in air is incident on an unknown substance with an incidence angle of 36 degrees. If the light ray is refracted at an angle 27 degrees in the substance, what is the index of refraction of the substance?
Calculate the energy in eV corresponding to the 595 nm of light inside a medium with refractive index 1. 8.
Light is incident on a piece of glass in air at an angle of 31 degrees from the normal. If the index of refraction of the glass is 1. 5, what is the angle in degrees that the refracted ray makes with the normal
