1 Reflection
2 Interference
3 Polarisation
4 Refraction
PHXII10:WAVE OPTICS

367890 The Brewsters angle \({i_b}\) for an interface should be:

1 \(30^\circ < {i_b} < 45^\circ \)
2 \(45^\circ < {i_b} < 90^\circ \)
3 \({i_b} = 90^\circ \)
4 \(0^\circ < {i_b} < 30^\circ \)

367891 When the angle of incidence is \(30^\circ \) on the surface of a glass slab, it is found that the reflected ray is completely polarised. The velocity of light in glass is

1 \(\sqrt 2 \times {10^8}\;m{s^{ - 1}}\)
2 \(3\sqrt 3 \times {10^8}\;m{s^{ - 1}}\)
3 \(2 \times {10^8}\;m{s^{ - 1}}\)
4 \(3 \times {10^8}\;m{s^{ - 1}}\)

367892 Assertion :
The angle of incidence of light is equal to Brewster's angle. then reflected ray is perpendicular to refracted ray.
Reason :
The refracted ray is polarized if the angle of incidence of light is equal to Brewster's angle.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
