Reference no: EM13649310

Four polarizing sheets are placed one behind the other, each onemaking an angle of 20o with the preceding one. A polarized beam of light with itselectric field making an angle of 30o with the first polarizing sheet impinges on this assembly. What is the ratio of the initial and final intensities? What is the direction ofthe electric field (with respect to initial direction) in the emerging light beam
