The phenomenon of polarization shows that light has _____ nature. 

What happens when the sunlight pass through a uniaxial crystal?

According to Malu’s Law, the intensity of polarised light emerging through the analyser varies with the angle θ as:

If the light is polarised by reflection, then the angle between reflected and refracted light is

The blue light from the sky has been polarised by:

When unpolarized light beam is incident from air onto glass (n = 1.5) at the polarizing angle ______

When a source of light is passed through 2 Polaroid filters and its axes are parallel, what is the effect of second filter?

Light is polarized to the maximum, when it is incident on a glass surface at an angle of incidence -

Two ideal polaroid sheets are arranged so that the angle between the pass-axis of the two sheets is θ. An unpolarised beam of light of intensity I₀ is incident on one of the polaroids. If the intensity of light emerging from the other polaroid is I₀ / 4, the angle θ is: 

When the angle of incidence is 60° on the surface of a glass slab, it is found that the reflected ray is completely polarized. The velocity of light in glass is
