Lag1989 problem number 22.17

Plane polarized light with an intensity of 100 W/m2 passes successively through two perfect polarizers, the planes of which are formed with the plane of oscillations in the initial beam of 20° and 50° (the angles are measured from the plane of oscillations clockwise when viewed along the beam). Determine the intensity of light and at the output of the second polarizer.
