whst is polarised light an unpolarised light explain in detail
Answers
A light wave that is vibrating in more than one plane is referred to as unpolarized light. ... Polarized light waves are light waves in which the vibrations occur in a single plane. The process of transforming unpolarized light into polarized light is known as polarization
Answer:
If the arbitrarily-chosen x- and y-components have a fixed phase difference between them, then the light is polarised (linear, circular or elliptical).
If the phase difference is unpredictable, and rapidly changing in time, then the light is unpolarised. Here, there is an equal distribution of electric field vectors for all directions, so if these are averaged out, there's no preferred direction of polarisation.
With truly monochromatic light, it's always completely polarised, since there is only light of one frequency - hence, the phase difference between x- and y-components is constant. So, you have the tip of the resultant electric vector tracing out an ellipse in space, and the ellipse can reduce to a circle or a straight line in special cases.
