Base your answers to questions 56 through 58 on the information and diagram below and on your knowledge of physics. A ray of monochromatic light (f = 5.09 x 1014 Hz) passes from medium X into air. The angle of incidence of the ray in medium X is 25 , as shown. Normal CT Singmable Air Medium X 250 56 Using a protractor, measure and record the angle of refraction in the air, to the nearest degree. [1] 57-58 Calculate the absolute index of refraction of medium X. [Show all work, including the equation and substitution with units.] [2] [12] P.S./Physics-June '19
