Question

Hi friends,
please state malus law​

Answer 1

Explanation:

• Malus law is crucial if we want to learn or understand the polarization properties of light. The law helps us to study the light intensity relation of polarizer-analyzer. Malus law is named after Étienne-Louis Malus, who in the year 1808 discovered that natural incident light could be polarized when it was reflected by a glass surface. He used calcite crystal for his experiment.

• After observing the results, he further put forth a concept that natural light consisted of the s- and p-polarization and that they were perpendicular to each other. Today, this law is used to define the intrinsic connection between optics and electromagnetism as well as demonstrate the transverse nature of electromagnetic waves.

Answer 2

the law stating that the intensity of a beam of plane-polarized light after passing through a rotatable polarizer varies as the square of the cosine of the angle through which the polarizer is rotated from the position that gives maximum intensity

plz thank my answer
