Question:
In Figure, unpolarized light is sent into a system of three polarizing sheets. The angles ?1, ?2 and ?3 of the polarizing directions are measured counterclockwise from the positive direction of the y axis (they are not drawn to scale). Angles ?1 and ?3 are fixed, but angle ?2 can be varied. Figure gives the intensity of the light emerging from sheet 3 as a function of ?2. (The scale of the intensity axis is not indicated.) What percentage of the light's initial intensity is transmitted by the system when ?2 = 30??
