Why does the intensity of gets halfed when it passes through second Polaroid

Posted by Pragya Verma 7 years, 11 months ago

CBSE > Class 12 > Physics

1 answers

Sudhanshu Saumya 7 years, 11 months ago

As some of the light wave is blocked by the Polaroid and it allowes only the waves propagating in one plane (plane polarised light) to pass through it so intensity of the light wave incident on Polaroid gets halved
