A beam of light is shining perpendicular on the film. If the wavelength of light incident on the film is 560 nm and the indices of refraction of gasoline and glass are 1.40 and 1.50, respectively, what is the minimum thickness of the film to see a bright reflection?
A) 500 nm B) 400 nm C) 300 nm D) 200 nm E) 100 nm Title: Re: A piece of glass has a thin film of gasoline floating on it. A beam of light is shining ... Post by: longhair on Feb 26, 2017 Content hidden
