What is the rays direction of travel in the glass Problem 23

Problem 23.10 Part A What is the ray\'s direction of travel in the glass? of glass. A light ray in tho air is incident on the water 54 o from the normal. 0glValue Units

Solution

Refraction equation

n_i * sin theta_i = n_r * sin theta_r

1.0 * sin 54 = 1.33 * sin theta_r

sin theta_r = sin 54 / 1.33

theta_r = 37.44 deg

--------------------------------------------------

1.33 * sin 37.44 = 1.52 * sin theta_r

sin theta_r = (1.33 * sin 37.44 ) / 1.52

theta_r = 32.14 deg
