Wave Optics Quiz 2

A ray of light passes from vacuum to a medium of refractive index n. The angle of incidence is found to be twice the angle of refraction. The angle of incidence is

If the polarizing angle for a given medium is 60°, then the refractive index of the medium is

A narrow beam of light in air is incident on glass at an angle of incidence of 58°. If the reflected beam is completely plane polarized, the refractive index of the glass is

Polarization of light CANNOT be produced by

A glass plate of refractive index 1.732 is to be used as a polarizer. Its polarizing angle is

Light transmitted through a Polaroid P has an intensity I and is incident on a crossed Polaroid P . The intensity of the light transmitted by P is

At points of constructive interference with maximum intensity of two coherent monochromatic waves (wavelength $\lambda$), the path difference between them is

Two sources of light are said to be coherent if light from them have

In a two-source interference pattern, the phase difference between the waves reaching a dark point in radian is (m = 1, 2, 3, …)

For destructive interference, the phase difference (in radian) between the two waves should be
