(a) Azimuth angle

(b) Elevation angle

(c) Brewster angle

(d) Inclination angle

I had been asked this question by my school teacher while I was bunking the class.

Answer 1

Right answer is (c) Brewster angle

The best explanation: The Brewster angle is the angle at which no reflection occurs in the medium of origin. It occurs when the incident angle is such that the reflection coefficient is equal to zero. The critical Brewster’s angles for diamond, glass and water are 67.5°, 57° and 53° respectively.
