What is the angle of the initial direction of polarization

Reference no: EM13297965

For the polarizers in the figure, suppose the incident light is linearly polarized, the transmitted intensity (through both polarizers) is 0.15×I0, and the axis of the second polarizer makes an angle ?=20° with the axis of the first polarizer. What is the angle (in degrees) the initial direction of polarization makes with the first polarizer? (Insert the number of degrees without unit.)
