4. A beam of light travels from air into an unknown liquid. The incident light ray strikes the air-liquid boundary at an angle of 35.3 degrees from the normal and the ray refracts into the liquid at an angle of 21.2 degrees from the normal. a) What is the index of refraction of the unknown liquid? b) If the ray of light started under the surface of the liquid and was directed towards the surface (towards the air-liquid boundary), what would be the critical angle for total internal reflection?
