Calculate the angle of refraction for light as it passes from air to each of the mediums at an incidence angle of 25°.
a. Water (n=1.33);
b. Diamond (n=2.42)
c. Plexiglas (n=1.51)
5. A ray of light travels from air into glass. The ray enters the glass at an angle of 36° from the normal. If the index of refraction for glass is 1.5, determine the angle of refraction.
