# Refracted Light Beam

A beam of light of wavelength 550nm, traveling in air, is incident on a slab of transparent material. The incident beam makes an angle of 40 degrees with the normal, and the refracted beam makes an angle of 26 degrees with the normal.

(a) Find the index of refraction on the material?

(b) What is the wavelength of this light in the slab?
