A horizontal beam of vertically polarized light of intensity 33.0 W/m² is sent through two polarizing sheets. The polarizing direction of the first is at 37.0° to the vertical, and that of the second is horizontal. What is the intensity of the light transmitted by the pair of sheets?
W/m²

Expert Solution

According to Maluls law

I = Io*cos^2

I1 = 33* cos^2 37

I1 = 21.04 W/m^2

After second polarizer

I2 = I1*cos^2 ( 90 - 37)

I2 = 21.04*cos^2 (53)

I2 = 7.62 W/m^2

the intensity of the light transmitted by the pair of sheets = 7.62 W/m^2

A particular beam of light, with an intensity of 440 W/m2, is linearly polarized at an angle of +5.00° to the vertical. You have three polarizers, which have their transmission axes aligned as follows: Polarizer A - the transmission axis is at +19.0° to the vertical; Polarizer B - the transmission axis is at +72.0° to the vertical; Polarizer C - the transmission axis is at +25.0° to the vertical. You will select two of these polarizers, and have the...
