Light with a wavelength A = 480 nm is incident on a transparent block with an angle of incidence of 429. The light travels at a speed of v = 2.42 x 108 m/s inside the block. The refractive index of air is nan, = 1.00. 61-5 Transparent Block Figure 1. A ray enters a medium of different refractive index at an angle 0; to the normal of the transparent block. Part 1) What is the angle of refraction for this ray? Part 2) What is the wavelength of this light in the medium? Part 3) What is the frequency of the light in the medium? f=:lz
