I = I0 cos2θ
- Malus’ law may be mathematically represented as I = I0 cos2θ, where I is the transmitted light intensity, I0 is the incident light intensity, and θ is the angle formed between the polarization axis and the incident light direction.

May 14, 2024 · Malus’ Law Formula. Consider a beam of light that is polarized after passing through the polarizer, and its electric field oscillates in one plane. The axis of the polarizer lies on this plane. Let this beam be incident on an analyzer whose axis makes an angle Ø with the axis of the polarizer.
The Malus law states that the intensity of the plane-polarised light that passes through the analyser is directly proportional to the square of the cosine of the angle between the plane of the polariser and the transmission axis of the analyser.
Apr 29, 2024 · Malus’s Law describes the behavior of polarized light when it passes through a polarizing filter. The law states that the intensity of polarized light after passing through a polarizing filter is directly proportional to the square of the cosine of the angle between the light’s initial polarization direction and the axis of the filter.
Jan 2, 2024 · What is the Equation for the Malus Law? The law is expressed as I(θ) = I o cos 2 θ , where I is the intensity of the polarized light after passing through a polarizer, I 0 is the initial intensity, and is the angle between the light’s initial polarization direction and the axis of the polarizer.
May 25, 2024 · We can calculate the light intensity, which passes through the ideal polarizer, as follows: intensity = initial intensity × cos²θ, where: initial intensity – Irradiance of the incident light; θ – Angle between the light polarization and the axis of the polarizer; and. intensity – Output irradiance.

Feb 20, 2022 · Equation \ref{27.9.1} is known as Malus’s law. Figure \(\PageIndex{6}\): The effect of rotating two polarizing filters, where the first polarizes the light. (a) All of the polarized light is passed by the second polarizing filter, because its axis is parallel to the first.
Quick Reference. A law concerning the polarization of light stating that the intensity of light passing through an analyser and polarizer is proportional to cos 2 θ, where θ is the angle through which the analyser has been rotated with respect to the polarizer.
