A light beam travels at 1.34×108 m/s in diamond. The wavelength of the light in diamond is 450 nm.

For the speed of light in vacuum/air remember we use the value, 3 x 108 m/s.

a)  What is the index of refraction of diamond at this wavelength?

b)  If the light ray hits the surface of the diamond at the angle of 16.0° from the normal, at which angle (from the normal) will it be refracted into air? (Recall the nair = 1.00)
