The Brewster's angle for the glass-air interface is (54 74)^ . If a ray of light passing from air to glass strikes at an angle of incidence 45^ , then the angle of refraction is [ (54 74)^ = 2 , 45^ = 1 2 ]
Options
- A⁻¹(0 5)
- B⁻¹(1)
- C⁻¹( 2 )
- D⁻¹ ( 1 2 )
Correct answer
A. ⁻¹(0 5)
Step-by-step solution
(D) n = 54.74= 2 2 = i r = 45^ r i = 45^ 2 = 1 2 2 = 1 2 =0.5 r = ⁻¹(0.5)
