- The component of the amplitude transmitted through the Polaroid along its transmission axis is A 0 cos θ. You know that the intensity of light is directly proportional to the amplitude squared. So, the intensity of light transmitted will be given by the expression: I = I 0 cos 2 θ

So, the intensity of light transmitted will be given by the expression: I=I_0 \cos ^2 \theta where $I_0$ is the intensity of the incident and $I$ is the transmitted intensity at an angle $\theta$ between the transmission axis of the Polaroid and the plane of the incident polarised wave.
Use this Physics calculator to calculate the intensity of polarized light when it passes through a linear polarizer at an angle θ to the grid lines using the M.
When unpolarized light is polarized with two polarizers, the intensity becomes $I=I_0\cos^2(θ)$ (Malus's law). But when unpolarized light is polarized with only one polarizer, the intensity is reduced to half the intensity of the unpolarized light.

Jan 30, 2024 · When the unpolarized light passes through the first filter, the intensity is cut in half and comes out polarized at \(0^o\). Then it passes through three successive filters, and applying Malus’s law for each \(30^o\) change of polarization angle brings in a factor of 0.75 for each polaroid.
