Light of wavelength 400 nm in air is transmitted into diamond, which has index of refraction 2.42. What is the wavelength of the light in diamond? Submit Answer Tries 0/10 What is the frequency of the light in diamond (in THz)? Submit Answer Tries 0/10 Post Discussion

A light source is embedded in a crystal with an unknown index of refraction. Light which originates inside the crystal and reaches the crystal-air interface with an angle of incidence greater than 30 degrees is totally internally reflected. What is the angle of refracted light when light is incident on the interface at exactly 30 degrees? Submit Answer Tries 0/10 What is the index of refraction of the crystal? Submit Answer Tries 0/10
