Compute the thickness of the glass

Reference no: EM13307002

A very thin sheet of glass (n=1.5) floats on the surface of water (n=1.33). When illuminated with white light at normal incidence, the reflected light consists predominantly of wavelengths 400nm and 560nm.

What is the thickness of the glass?

What wavelengths would be visible if a thin layer of water of the same thickness were spread out on top of a thick piece of glass?
