White light containing the wavelengths between 420 and 720 nm traveling in the air falls on a thin layer n1 = 1.5 and a thickness of 0.000001 m. If this layer is placed on another thin film n2 = 1.4, determine the wavelengths of the light that is not reflected in the air.

Optics
A layer of water covers an unknown transparent material X. At the angles shown in the figure below, a ray of light travels from material X to water which has an index of refraction n = 1.33.
(a) Show your calculation of the index of refraction of the unknown material X.
Eventually the light ray will exit water into air, which has an index of refraction n = 1.00.
(b) Show your calculation of the angle at which the light ray will emerge into air.
