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.

Jun 19, 2024 · Étienne-Louis Malus (born June 23, 1775, Paris—died Feb. 23, 1812, Paris) was a French physicist who discovered that light, when reflected, becomes partially plane polarized; i.e., its rays vibrate in the same plane. His observation led to a better understanding of the propagation of light.

A follower of Laplace, both his statement of the Malus's law and his earlier works on polarisation and birefringence were formulated using the corpuscular theory of light. [1] His name is one of the 72 names inscribed on the Eiffel tower .
Malus's work on polarization was published in 1809, and in 1810, his theory of double refraction of light in crystals appeared in print as well. Included among Malus's published work is Malus's law, a mathematical means of predicting the intensity of light transmission through a pair of polarizing filters.

May 28, 2024 · Malus’s Law plays a fundamental role in the field of optics, particularly in the study of polarized light. Discovered by Étienne-Louis Malus in 1809, this law describes how the intensity of light changes as it passes through a polarizing filter.
(Figure Presented) Étienne-Louis Malus (see picture) serendipitously discovered the polarization of light by reflection nearly 200 years ago. The conditions of the re-creation of his benchmark experiment are analyzed.

Malus's Law: Number of rays in the ordinary (resp. extra-ordinary) beam is proportional to the square of the cosine ( resp . sine) of the angle between the plane of polarization of the incident beam and the crystal's principle section.
