Sample Problem 7.5
A ray of light is incident on the surface of a crown glass plate at an angle of 30° with the
normal. Determine the angle between the refracted ray and the reflected ray.
Given: 0,=30°
1crown glass
(from table 7-1)=1.52
Nair=1.00
Solution:
Based on the figure, 0=180°–0,'– 0,. Because the angle of
reflection must be equal to the angle of incidence, 0,'=30°. Using
Snell's law in solving for the angle of refraction 02,
0, i 0!
air
n, sin 6, = n, sin 0,
(1.00) sin 30° = (1.52) sin0,
= 19.2° 19°.
crown glass
plate
Therefore, 0=180° – 30° – 19.2°=130.8°~131°.
