I = I0 cos2θ
- Malus’ law may be mathematically represented as I = I0 cos2θ, where I is the transmitted light intensity, I0 is the incident light intensity, and θ is the angle formed between the polarization axis and the incident light direction.

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.
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.
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:
Feb 20, 2022 · Equation \ref{27.9.1} is known as Malus’s law. Figure \(\PageIndex{6}\): The effect of rotating two polarizing filters, where the first polarizes the light. (a) All of the polarized light is passed by the second polarizing filter, because its axis is parallel to the first.
Malus's Law. The intensity of unpolarised light is reduced as a result of polarisation. If unpolarised light of intensity I0 passes through a polariser, the intensity of the transmitted polarised light falls by a half. The first filter that the unpolarised light goes through is the polariser.
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.
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.
