The angle of incidence of light is equal to Brewster's angle, then
1 (1) and (4) are true
2 (1) and (2) are true
3 (1) and (3) are true
4 (2) and (4) are true
Explanation:
: The refracted ray is perpendicular to the refracted ray. Refracted ray is also polarised the vibration of the reflected rays are perpendicular to the plane of incident and that of the refracted ray are parallel.

Which of the following phenomenon is not shown by sound waves?
1 Diffraction
2 Interference
3 Polarisation
4 None of these
Explanation:
: As sound waves are longitudinal waves they does not exhibit polarization phenomenon it is exhibit by the transverse wave only. Diffraction and interference takes place in sound wave.

In the propagation of light waves, the angle between the direction of vibration and plane of polarisation is
1 \(0^{\circ}\)
2 \(90^{\circ}\)
3 \(45^{\circ}\)
4 \(80^{\circ}\)
Explanation:
: The angle between the direction of propagation and the plane of polarization is zero degree.

When ordinary light is made incident on a quarter wave plate, the emergent light is
1 linearly polarised
2 circularly polarised
3 elliptically polarised
4 unpolarised
Explanation:
: A quarter-wave plate is basically used for the elliptical polarization of the unpolarized light incident over it. The Quarter-wave plate produces the electric field at the various angle about the axis of the light and thereby making the light elliptically polarized.
