A glass lens has a scratch-resistant plastic coating on it. The speed of light in the glass is 0.720c, and the speed of light in the coating is 0.80c. A ray of light in the coating is incident on the plastic–glass boundary at an angle of 18.3° with respect to the normal. At what angle with respect to the normal is the ray transmitted into the glass?

Sometimes a nonreflective coating is applied to a lens, such as a camera lens. The coating has an index of refraction between the index of air and the index of the lens. The coating cancels the reflections of one particular wavelength of the incident light. Usually, it cancels green-yellow light (λ 546.0 nm) in the middle of the visible spectrum. (a) Assuming the light is incident perpendicular to the lens surface, what is the minimum thickness of the coating in...
