A lens made of glass (ng = 1.52) is coated with a thin film of (ns = 1.45 ) of thickness t. Visible light is incident normally on the coated lens as in the figure below.
a) For what minimum value of t will the reflected light of wavelength 554 nm (in air) be missing? nm
b) Are there other values of t that will minimize the reflected light at this wavelength? Explain.
Answers: Part (a): Minimum value of t for specified situation, t =... View the full answer
