What is Malus Law?
According to Malus’s rule, the square of the cosine of the angle formed between the polarizer’s plane and the analyzer’s transmission axes determines how much plane-polarized light changes in intensity as it passes through the device.
Malus’s Law is significant in optics and helps in understanding how polarized sunglasses work, how stress patterns in transparent materials can be studied, and in various other applications where control of light polarization is required.
Who is Etienne-Louis Malus?
Étienne-Louis Malus was a mathematician, physicist, engineer, and commander from France. Malus was born in France’s Paris. He served at the Institut d’Égypte’s mathematics department and took part in Napoleon’s invasion of Egypt.

Malus Law
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.
In this article, we will discuss the concept of Malus Law which describes the intensity of change in the intensity of polarized light.
