The Brewster's angle _B for air-glass interface should be such that (refractive index of glass = 3 2 )
Options
- A_B = 90^
- B45^ < _B < 90^
- C30^ < _B < 45^
- D0^ < _B < 45^
Correct answer
B. 45^ < _B < 90^
Step-by-step solution
According to Brewster's law, the tangent of the polarizing angle (Brewster's angle) is equal to the refractive index of the medium. _B = Given = 3 2 = 1.5 _B = 1.5 We know that 45^ = 1 and 90^ . Since 1 45^ Answer: 45^ < _B < 90^
