Question

What is Polaroid? Write any two uses of it. How will you identify the polarised light, the partially polarised light and the unpolarised light?

Answer 1

Polaroid is the material that polarize the light. Polarization is the restriction the vibration of light in the particular plane.

Uses of Polaroid,

1) Polaroid are used on spectacles to reduce glare.

2) Plane polarized light is commonly used in chemical analysis to determine handedness of molecules.

Polarized light waves are light waves in which the vibrations occur in a single plane

partially polarized light can be described as the mixture of polarized and unpolarized light.

unpolarized light, vibrations take place randomly in directions perpendicular to the direction of the wave.
