Aray of monochromatic light (f=5.09x10^14 hz) passes through air and a rectangular transparent block calculate the absolute index of refraction for the medium of the transparent block
angle of incidence of the light ray as it enters the transparent block from air =40 degrees
the angle of refraction of the light ray as it enters the transparent block from air = 20 degrees
calculate the absolute index of refraction from the medium of the transparent block
