Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFA light wave that has vibrations in more than one plane is known as unpolarized light.
- Polarized waves are light waves in which the vibrations occur in a single plane.
- A Nicol prism is made up of two prisms of calcite (CaCO3).
- Nicol prism is designed in such a way that it eliminates the ordinary rays by total internal reflection and only allow the extraordinary rays to transmit through it.
Notes:
- Nicol prism is used for producing a polarised beam of light from an un-polarised beam. Hence, option 2 is correct.
- It is based on the principle of action which involves refraction as it passes into the lower half of the prism.
- It leaves the prism as polarised light after undergoing another refraction as it exits the far right side of the prism. Thus its action is based on double refraction.
