What is polarized light. Explain how plane polarized light is obtained by reflection and refraction.

Plane polarized light can be obtained by using

What is meant by plane polarized light?

When light is polarised by reflection from a transparent surface. a) reflection and refracted rays are mutually perpendicular b) both reflected and refracted rays are plane polarised c) refraction ray is partially polarised d) the R.I., of transparent surface is equal to tangent of Brewster.s angle

(a) When an unpolarized light of intensity I_(0) is passed through a polaroid , what is the intensity of the linearly polarized light ? Does it depend on the orintation of the polaroid ? Explain your answer. (b) A plane polarized beam of light is passed through a polaroid . Show graphically the variation of the intensity of the transmitted light with angle of rotation of the polaroid in complete one rotation.

What is meant by refraction of light?

A : Light coming from numbers of calculator.s L.C.D display is polarised. R : The reflected light cannot be polarized when light is incident normal to the plane surface.

When a light ray is incident on a medium of refractive index 4/3, reflected light is found to be 100% polarized. What is the angle of refraction in degrees? (tan 53^@ = 4/3) .

Assertion (A) : The unpolarised light and polarized light can be distinguished from each other by using Polaroid. Reason (R ) : A Polaroid is capable of producing plane polarized beams of light.

A plane polarized light is incident on an analyser and when it is rotated to complete one rotation, one observes

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