Question

If the angle between the pass axis of the polarizer and the analyser is 45degree write the ratio

Answer 1

In acoordance to Malu’s law, the intensity of transmitted light after passing through the analyser will be,

I (θ) = I0cos2θ

Hereθ =45°

So,I (θ) = I0cos2(45°) = I0/2

Thus, I0/I = 2

From the above observation we conclude that,the ratio of intensities of orginal light and the transmitted light after passing through the analyser will be 2.
