Answer 1

S.No.	Polarised light	Unpolarised light
1.	Consists of waves having their electric field vibrations in a single plane normal to the direction of ray.	Consists of waves having their electric field vibrations equally distributed in all directions normal to the direction of ray.
2.	Asymmetrical about the ray direction	Symmetrical about the ray direction
3.	It is obtained from unpolarised light with the help of polarisers	Produced by conventional light sources.
