Long answers question
Distinguish between a plane polarized and unpolarized light.
Show that: tan p=n
n=refractive index of the medium
p=angle op polarization of polarizing angle.
What do you mean by polarization of electromagnetic waves? Discuss the polarization of light by refection and show that , where the symbols have their usual meanings.
