Malus Law:
The intensity of polarized light transmitted through the analyzer varies as the square of the
cosine of the angle between the plane of transmission of the polarizer and analyzer.
I = I0cos2θ Where θ is the angle between the axis of the polarizer and analyzer.

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. Expand. Also called law of Malus, Malus cosine-squared law.

Malus law states that the intensity of polarised light(wave)  after passing through analysers is squre of cosine of angle between polariser and analyser multiply by the original intensity.
I.e I=IoCOS^2(thita)

When a completely plane-polarised light beam from a polariser is incident on an analyser the intensity of light emerging from analyser varies as square of the cosine of the angle between the planes of transmission of analyser and the polariser.
