Question

A beam of light is incident upon a flat piece of glass (n =1.50) at an angle of incidence of 45 degrees. Part of thebeam is transmitted and part is reflected. What is the anglebetween the reflected and transmitted rays? a. 28 degrees b. 73 degrees c. 107 degrees d. 152 degrees A beam of light is incident upon a flat piece of glass (n =1.50) at an angle of incidence of 45 degrees. Part of thebeam is transmitted and part is reflected. What is the anglebetween the reflected and transmitted rays? a. 28 degrees b. 73 degrees c. 107 degrees d. 152 degrees

Explanation / Answer

n = 1.50, = 45o, reflected angle = = 45o, refracted angle : sin = n*sin, so = 28o the required angle = 180 - - = 107o answer: c
