Question

two polaroids are oriented with their plane perpendicular to the incident light and transmission Axis making and angle of 60 degree with each other what will be the fraction of incident unpolarised light transmitted through the system??​

when unpolarized light of intensity passes through the first polarised light then intensity of the emergent light is given by :-

I = Io/2

now, the light of intensity I falls on the second polaroid whose axis is inclined at the angle of 60 ° with the axis of the first polaroid the intensity of emergent light is :-

I' = I cos^2 60°

= Io/2(1/2)^2

= Io/8

fraction of incident light transmitted through the system :-

I'/Io = 1/8

= 1/8 × 100

= 12.5
