The average intensity of light emerging from a polarizing sheet is 0.775 W/m2, and that of the horizontally polarized light inci
rewona [7]

Answer:

the transmission axis of polarizing sheet makes an angle of \Theta =26.74^{\circ} with the horizontal        

Explanation:

We have given that intensity of light incident on the sheet I_0=0.970W/m^2

Average intensity of light emerging from a polarizing sheet I=0.775W/m^2

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

Intensity of light polarizing from sheet is equal to I=I_0cos^2\Theta

So 0.775=0.970cos^2\Theta

cos^2\Theta =0.798

cos\Theta =0.893

\Theta =26.74^{\circ}

So the transmission axis of polarizing sheet makes an angle of \Theta =26.74^{\circ} with the horizontal
