The average intensity of light emerging from a polarizing sheet is 0.775 W/m2, and that of the horizontally polarized light incident on the sheet is 0.970 W/m2. Determine the angle that the transmission axis of the polarizing sheet makes with the horizontal.

the transmission axis of polarizing sheet makes an angle of with the horizontal        

Explanation:

We have given that intensity of light incident on the sheet

Average intensity of light emerging from a polarizing sheet

We have to find the angle between transmission axis with the horizontal

Intensity of light polarizing from sheet is equal to

So

So the transmission axis of polarizing sheet makes an angle of with the horizontal
