What is Malus' law ?

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 the 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.

How to Calculate Malus’ law?

Malus’ law calculator uses Resultant Intensity=Intensity 1*(cos(Theta))^2 to calculate the Resultant Intensity, Malus’ law states that the intensity of plane-polarized light that passes through an analyzer varies as the square of the cosine of the angle between the plane of the polarizer and the transmission axes of the analyzer. Resultant Intensity and is denoted by I symbol.

How to calculate Malus’ law using this online calculator? To use this online calculator for Malus’ law, enter Theta (ϑ) and Intensity 1 (I1) and hit the calculate button. Here is how the Malus’ law calculation can be explained with given input values -> 6.75 = 9*(cos(30))^2.

FAQ

What is Malus’ law?
Malus’ law states that the intensity of plane-polarized light that passes through an analyzer varies as the square of the cosine of the angle between the plane of the polarizer and the transmission axes of the analyzer and is represented as I=I1*(cos(ϑ))^2 or Resultant Intensity=Intensity 1*(cos(Theta))^2. Theta is an angle that can be defined as the figure formed by two rays meeting at a common endpoint and Intensity 1 is the quantity of energy the wave conveys per unit time across a surface of unit area, and it is also equivalent to the energy density multiplied by the wave speed.
How to calculate Malus’ law?
Malus’ law states that the intensity of plane-polarized light that passes through an analyzer varies as the square of the cosine of the angle between the plane of the polarizer and the transmission axes of the analyzer is calculated using Resultant Intensity=Intensity 1*(cos(Theta))^2. To calculate Malus’ law, you need Theta (ϑ) and Intensity 1 (I1). With our tool, you need to enter the respective value for Theta and Intensity 1 and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Resultant Intensity?
In this formula, Resultant Intensity uses Theta and Intensity 1. We can use 7 other way(s) to calculate the same, which is/are as follows -
  • Resultant Intensity=Intensity 1+Intensity 2+(2*sqrt(Intensity 1*Intensity 2)*cos(Phase Difference))
  • Resultant Intensity=(sqrt(Intensity 1)+sqrt(Intensity 2))^2
  • Resultant Intensity=(sqrt(Intensity 1)-sqrt(Intensity 2))^2
  • Resultant Intensity=Intensity 1+Intensity 2
  • Resultant Intensity=4*Intensity 1*(cos(Phase Difference/2))^2
  • Resultant Intensity=Intensity 1+Intensity 2+2*sqrt(Intensity 1*Intensity 2)*cos(Phase Difference)
  • Resultant Intensity=Power*Area
