A polarized light of intensity ( I₀ ) is passed through another polarizer whose pass axis makes an angle of ( 60^ ) with the pass axis of the former. What is the intensity of emergent polarized light from second polarizer?

Step-by-step solution

According to Malus Law, we have [ I=I₀ ² ] where, ( I ) is intensity of emergent polarised light; ( I₀ ) is intensity of incident polarised light; ( ) is angle between pass axis of both polarisers Here ( =60^ ) Therefore ( I=I₀( 60)²=I₀ ( 1 2 )²= I₀ 4 ) Thus, intensity of emergent polarised light from second polarizer ( = I₀ 4 )
