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.
Malus's law states that if the analyser is rotated by an angle θ with respect to the polariser, the intensity of the light transmitted by the analyser is. Malus’s law equation. Recall that intensity is the power per unit area and measured in W m-2.
6 days ago · 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.

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.
What is the malus law equation? The law of malus states that the intensity of a plane-polarized light that passes through an analyzer varies as the square of the cosine of the angle between the plane of the polarizer and the transmission axes of the analyzer.
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.
