Question

A polaroid making an angle 60 with electric vectro'

Answer 1

The phenomenon of the polarization is based  upon the transverse of the wave. As we know that there are longitudinal wave and transverse wave.

• The longitudinal wave cannot be polarised only transverse wave can be polarised.
• Which means it depends upon transverse nature of the light.

• The angle 60 is due if the wave incident at 90 angle and polariod making 60 angle with it gives the transmission of 30 between them.
