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 (= 549.0 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 terms of the wavelength of light in that coating? (Use the following as necessary: A.) W = 4 (b) If the coating's index of refraction is 1.44, what should be the minimum thickness of the coating? 95.3 X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m
