50.An unpolarized light passes through three polarizing sheets whose polarizing directions make an angle of 30^(@) 60^(@) and 30^(@) with y axis in same sense.What fraction of initial intensity is transmitted by the system?

When unpolarized light is passed through a polarizer , its intensity

When its unpolarized light is passed through a polarizer, its intensity

A horizontal beam of vertically polarized light of intensity 43 W//m^(2) is sent through two polarizing sheets. The polarizing direaction of the first is 60^(@) to the vertical, and that of the second is horizontal. The intensity of the light transmitted b y the pair of sheets is (nearly)

A polarized light of intensity I_(0) is passed through another polarizer whose pass axis makes an angle of 60^(@) with the pass axis of the former. What is the intensity of polarized light from second polarizer ?

An unpolarizing beam of light is incident on a group of four palarizing sheets, which are arranaged in such a way that the characteristic direction of each polarizing sheet makes an angle of 30^(@) with that of the preceding sheet. What fraction of incident unpolarized light is transmitted ?

A polarized light of intensity I_(0) is passed through another polarizer whose pass axis makes an angle of 60^(@) with the pass axis of the former, What is the intensity of emergent polarized light from second polarizer?
