What is its index of refraction

Reference no: EM13319938

A pair of eyeglasses has an index of refraction nglass = 1.52. It is covered with an antireflection layer that has a thickness of 120 nm and an index of refraction that is less than nglass. If the antireflection layer is designed to minimize reflection in the middle of the visible spectrum (wavelength-lambda ( %u03BB )= 565 nm), what is its index of refraction?
