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.

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.
May 14, 2024 · Malus’ law states that the intensity of plane-polarized light passing through an analyzer varies as the square of the cosine of the angle between the transmission axes of the polarizer and analyzer.
Jun 17, 2024 · Malus law deals with the polarization properties of light. It helps us to study the relation of the intensity of light and the polarizer-analyzer. The law was derived by Etienne-Louis Malus in 1808. He discovered that natural light could be polarized when reflected by a glass surface.

Apr 29, 2024 · Learn about Malus's Law, which describes the intensity of polarized light transmitted through an analyzer relative to the angle of polarization, with its formula, derivation, and practical examples.
Malus's Law. According to malus, when completely plane polarized light is incident on the analyzer, the intensity I of the light transmitted by the analyzer is directly proportional to the square of the cosine of angle between the transmission axes of the analyzer and the polarizer. i.e I ∞ cos 2 θ.
Malus' law: I t = I o cos 2 θ where θ is the angle between the polarization direction of the incident light and the transmission axis of the polarizer. When unpolarised light is passsed through a polarising filter its intensity is halved and only light parallel to the grid within the polarising filter is allowed through.
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.
