A polarizer is used to

Through which character we can distinguish the light waves from sound waves

The angle of polarisation for any medium is 60°, what will be critical angle for this?

The angle of incidence at which reflected light is totally polarized for reflection from air to glass (refractive index n) is

A polaroid is placed at 45° to an incoming light of intensity I₀ . Now the intensity of light passing through polaroid after polarisation would be

Plane polarised light is passed through a polaroid. On viewing through the polaroid we find that when the polaroid is given one complete rotation about the direction of the light, one of the following is observed

Out of the following statements which is not correct?

A ray of light is incident on the surface of a glass plate at an angle of incidence equal to Brewster\'s angle ϕ. If µ represents the refractive index of glass with respect to air, then the angle between reflected and refracted rays is

Figure represents a glass plate vertically on a horizontal table with a beam of unpolarised light falling on its surface at the polarising angle of 57° with the normal. The electric vector in the reflected light on screen S will vibrate with respect to the plane of incidence in a

A beam of light AO is incident on a glass slab (µ = 1.54) in a direction as shown in figure. The reflected ray OB is passed through a Nicol prism. On viewing through a Nicole prism, we find on rotating the prism that
