Answer to Question #102669 in Optics for sakshi

Question

What kind of polarised light will you get if two plane polarised light waves of equal amplitude but having a phase difference of 90º are superposed? Justify your answer. Explain why unpolarised light reflected by a pile of plates is linearly polarized.

Answer 1

If two lane polarized light wave with equal amplitude and having phase difference 90 are getting superimposed, then the tip of E describes a circle.The electric field rotate in time with a fixed magnitude.

when polarized light passing through the polarizer, then the intensity of the light is getting reduced, only 8% of light is getting polarized, if we are using the pile of plates, then after the multiple polarized, the intensity of the polarized is getting increase.
