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

Answer:

The polarized light will be circularly polarized light

Explanation:

As we know that the two waves are at 90 degree phase difference so the equations of two waves is given as

$x = A sin(\omega t - kz)$

$y = A sin(\omega t - kz + 90)$

$y = A cos(\omega t - kz)$

now from above two equations we have

$x^2 + y^2 = 1$

so here the locus of two waves is circular

so the plane polarized light is circular polarized light
