I=I₀cos² (θ)
- This relationship I=I₀cos² (θ), is known as Malus’s Law. It quantitatively describes how the intensity of polarized light diminishes as the angle between the light’s initial polarization direction and the filter’s axis increases.

Why is Malus' law called Malus law?
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.
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.
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.
Jan 2, 2024 · What is the Equation for the Malus Law? The law is expressed as I(θ) = I o cos 2 θ , where I is the intensity of the polarized light after passing through a polarizer, I 0 is the initial intensity, and is the angle between the light’s initial polarization direction and the axis of the polarizer.
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.
Apr 29, 2024 · Malus Law Formula. The formula for Malus’s Law, which describes how the intensity of polarized light changes as it passes through a polarizing filter, is given by: I=I₀ cos²(θ) Where:
Jun 17, 2024 · 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.
