Question

At the angle of polarization, p, the angle between the reflected and the refracted beam is __________

(a) p

(b) π

(c) π /2

(d) p/2

I had been asked this question in examination.

I'd like to ask this question from Production of Plane Polarised Light topic in division Polarisation of Engineering Physics II

Answer 1

Correct choice is (c) π /2

The explanation is: If the angle of incidence is equal to p, the angle made by the refracted beam with the x-axis would be π /2 – p. The refracted beam would make an angle p with the x-axis. Thus, the angle between the two rays would be π /2.
