Elisabeth coats a glass plate (index of refraction of 1.5) with a thin film of a material that has an index of refraction n = 1.40. When white light shines perpendicularly on the film, the reflected light from the surface appears green with a wavelength of 524 525 nm. What is the thickness of the coating in nanometers? Please give your answer as a whole number.
