$A$ beam of polarized light is sent through a system of two polarizing sheets. Relative to the polarization axis of that incident light, the polarizing axes of the sheets are at angles $\theta$ for the first sheet and $90^{\circ}$ for the second sheet. If $0.10$ of the incident intensity is transmitted by the two sheets, what is $\theta$ ?

Key Concepts

Malus's Law

Malus's Law quantifies the transmitted intensity of polarized light as it passes through a polarizer. It states that the intensity is proportional to the square of the cosine of the angle between the light's polarization direction and the polarizer's axis, forming the basis for calculating how much light is transmitted in such optical systems.

Double Polarizer System

In a double polarizer system, light passes sequentially through two polarizers with different orientations. The first polarizer alters the light's polarization, and the transmitted intensity is then further modified by the second polarizer. Calculating the net transmitted intensity involves applying Malus's Law to each stage, often requiring trigonometric relationships to account for the angular differences between the polarizers.

Polarization

Polarization is the property of light that describes the direction in which its electric field oscillates. When light is polarized, its oscillations occur in a specific plane, which influences how the light interacts with devices such as polarizing filters that only transmit light aligned with their axis.
