A beam of unpolarized light is incident on a polarizer with an angle of incidence of 60 degrees. The polarizer is rotated, and the intensity of light passing through the polarizer is measured for various angles of rotation. The intensity of the transmitted light is found to be 50% of the incident light when the polarizer is rotated by 30 degrees. What is the angle between the transmission axis of the polarizer and the direction of polarization of the incident light?
