What is linearly polarised light?

What is elliptically polarised light?

In case of linearly polaised light ,the magnitude of the electric field vector:

What is an unpolarised ligth ?Explain with the help of a suitable ray diagram,how an unpolarised light can be polarised by reflection from a transparent medium.Write the expression for Brewster angle in terms of the refractive index of the denser medium.

Defien a linearly polarised or plane polarised light.Why is the phenomenon of polarisation not observed by sound waves?

What is meant by plane polarised ligth ?Which type f waves show the property of polarisation ?Briefly discuss: polarisation by scattering and

Can reflection result in plane polarised light if the light is incident on the interface from the side with higher refractive index?

Which special characteristic of ligth is demonstrated only by the phenomenon of polarisation?Distinguihs clearly between linearly polarised light and unpolarised light.
