1) Listen Base your answer to the question on the diagram below, which represents a ray of monochromatic light (f = 5.09 x1014 hertz) in air incident on flint glass. Normal 35° Air Flint glass What happens to the light from the incident ray that is not refracted or absorbed? 1 It is reflected and converted to mechanical energy. 2. It is reflected, absorbed and some energy is lost. 3. It is all destroyed. 4. It is slowed down, dissolved and reflected.
