Unformatted text preview: therefore 2 2 1 1 2 1 1 2 2 8 cos cos 60 . I I I I = = = The light is now polarized at an angle 2 20 = clockwise from the y axis. This light makes an angle of 2 3 60 = with the polarization axis of the third sheet. The transmitted intensity after all three sheets is therefore 2 2 1 1 3 2 2 3 8 32 cos cos 60 . I I I I = = = Thus, 3.1% of the lights initial intensity is transmitted through to the end. 49. The light transmitted through both sheets has an intensity of 2 1 2 2 cos , I I = where I is the intensity of the incident beam and is the angle between the polarization axes of the sheets. For 1 2 3 , I I = they must be at an angle of ( 29 1 2 3 cos 35 .= =...
