Malus-Dupin theorem

ID: malus-dupin-theorem

The Malus-Dupin theorem, also known simply as Malus's law, is a principle in optics that describes the intensity of polarized light as it passes through a polarizing filter. It states that the intensity of light transmitted through a polarizer is proportional to the square of the cosine of the angle between the light's initial polarization direction and the axis of the polarizer.
