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. Malus’ law has been named after Étienne-Louis Malus, who was a French engineer, physicist, and mathematician.
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.
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.
What Is Malus Law? Malus law states that the intensity of plane-polarised light that passes through an analyser varies as the square of the cosine of the angle between the plane of the polariser and the transmission axes of the analyser.

- Lightwaves can be polarised. The phenomenon of polarisation takes place only in the transverse nature of waves. So, sound waves cannot be polarised.
- The Malus law is named after Etienne Malus, who published this law in 1809.
However, in order to obtain the intensity, Malus squared the amplitude relation so that the intensity equation I(θ) of the reflected polarized light was where I 0 = A 0 2 . this equation is known as Malus’s Law.
Jan 2, 2024 · Malus Law, also known as Malus Law of Polarization, is a fundamental principle in optics that describes how the intensity of polarized light changes as it passes through a polarizer. It is named after Étienne-Louis Malus, a French physicist who formulated the law in 1808.
Dec 26, 2022 · Malus law states that the intensity of the light transmitted through a polarizer is proportional to the square of the cosine of the angle between the polarizer and the plane of polarization of the incoming light.
