Задача 40149.

A polarizer was placed in the path of partially polarized light. When the polarizer was rotated through an angle of 60° from the position corresponding to the maximum transmission, the intensity of the transmitted light decreased by k = 3.0 times. Find the degree of polarization P of the incident light.
