37. The angle between the direction of polarization of the light incident on the Frst polarizing sheet and the polarizing direction of that sheet is θ 1 =70 .I f I 0 is the intensity of the incident light, then the intensity of the light transmitted through the Frst sheet is I 1 = I 0 cos 2 θ 1 =(43W / m 2 )cos 2 70 =5 . 03 W / m 2 .

Unformatted text preview: with the vertical and an angle of 2 = 20 with the horizontal. 2 is the angle it makes with the polarizing direction of the second polarizing sheet. Consequently, the transmitted intensity is I 2 = I 1 cos 2 2 = (5 . 03 W / m 2 ) cos 2 20 = 4 . 4 W / m 2 ....
