Question

Unpolarized light of intensity x is incident on a polarising sheet. Intensity of light which does not get transmitted is (A) x (B) (x/2) (C) (x/4) (D) Zero

Tardigrade Admin · Accepted Answer

Polariser transmits energy travelling along a single plane. Energy transmitted is (x/2) Hence energy left behind is x-(x/2)=(x/2)

Q. Unpolarized light of intensity $x$ is incident on a polarising sheet. Intensity of light which does not get transmitted is

$x$

$\frac{x}{2}$

$\frac{x}{4}$

Zero

Polariser transmits energy travelling along a single plane.
Energy transmitted is $\frac{x}{2}$
Hence energy left behind is $x - \frac{x}{2} = \frac{x}{2}$

Q. Unpolarized light of intensity x is incident on a polarising sheet. Intensity of light which does not get transmitted is

x

2x​

4x​

Zero

Polariser transmits energy travelling along a single plane. Energy transmitted is 2x​ Hence energy left behind is x−2x​=2x​

Q. Unpolarized light of intensity $x$ is incident on a polarising sheet. Intensity of light which does not get transmitted is

$x$

$\frac{x}{2}$

$\frac{x}{4}$

Polariser transmits energy travelling along a single plane.
Energy transmitted is $\frac{x}{2}$
Hence energy left behind is $x - \frac{x}{2} = \frac{x}{2}$
