What dose a polaroid consist of?
Show, using a simple polaroid, that light waves are transverse in nature. Intensity of light coming out of a polaroid does not change irrespective of the orientation of the pass axis of the polaroid. Explain why.
How does one demonstrate, using a suitable diagram, that unpolarised light when passed through a Polaroid gets polarised?
A beam of unpolarised light is incident on a glass-air interface. Show, using a suitable ray diagram, that light reflected from the interface is totally polarised, when μ = tan iB, where μ is the refractive index of glass with respect to air and iB is the Brewster's angle.
Show, with the help of a diagram, how unpolarised sunlight gets polarised due to scattering.
The refractive indices of water for red and violet colours are 1.325 and 1.334 respectively.
Find the difference between the velocities of rays for these two colours in water. (c = 3 × 108 m/s)
What is the value of refractive index of a medium of polarising angle 60°?

Unpolarised light is incident on a polaroid. How would the intensity of transmitted light change when the polaroid is rotated?
Light transmitted by Nicol prism is ______.
Discuss about Nicol prism.
What is normal focusing?
The reflected light is found to be plane polarised when an unpolarized light falls on a denser medium at 60° with the normal. Find the angle of refraction and critical angle of incidence for total internal reflection in the denser to rarer medium reflection.
