If a light beam shows no intensity variation when transmitted through a polarised, which is rotated, does it mean that light is unpolarized ?

(a) What is plane polarised light? Two polaroid sare placed at 90^(@) to each other and the transmitted intensity is zero. What happens when one more polaroid is placed between these two, bisecting the angle between them? How will the intensity of transmitted light vary on further rotating the third polaroid? (b) If a light beam shows no intensity variation when transmitted through a polaroid which is rotated, does it mean that the light is un-polarised? Explain briefly.

What is is plane polarised light ? Two polaroids are placed at 90^(@) to each other and the transmitted intensity is zero. What happens when one more polaroid is placed between these two, bisecting the angle betweeen them ? How will the intensity of transmitted light vary on further rotating the third polaroid ? (b) If a light beam shows no intensity variation when trasmitted through a polaroid which is rotated, does it mean that the light is un-polarised ? Explain briefly.

Why does unpolarised light from a source show no variation in intensity when viewed through a polariod which is rotated? Show with the help of a diagram, how unpolarised light from sun gets linearly polarised by scattering.

Define the term 'linearly polarised light'. When does the intensity of transmitted light become maximum, when a polaroid sheet is rotated between two crossed polaroids ?

Define the term 'linearly polarised light'. When does the intensity of transmitted light become maximum, when a polaroid sheet is rotated between two crossed polaroids ?

Define the term 'linearly polarised light' . When does the intensity of transmitted light become maximum when a polaroid sheet is roatated between two crossed polaroids?

When light is polarised, how does its intensity change?

(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.
