Irradiance of light after polarizer¶
Malus’s law states that the irradiance of linearly polarized light that passes through a polarizer is proportional to its initial intensity, transparency coefficient of the polarizer and square cosine of the angle phi between the light’s initial polarization direction and the axis of the polarizer.
