Light that is polarized to be horizontal passes through horizontal polarizers. This separates it from the other directions of light, since normal white is not polarized and is in all directions.
When unpolarized light passes through a polarizer crystal, it becomes polarized in one direction. This polarized light then passes through the second crystal. If the two crystals are arranged parallel to each other, they will have a similar polarization axis, allowing the light to pass through. If the second crystal is rotated slightly, it will act as a polarizer and block some of the light, demonstrating the effect of polarization.
A linear polarizer can block or reduce the transmission of circularly polarized light by filtering out one of the two orthogonal components of the circular polarization. This results in a change in the polarization state of the light passing through the polarizer.
Light that passes through a horizontal polarizing filter will have its electric field components aligned with the filter's direction, allowing only the component parallel to the filter to pass through. The intensity of the light will be reduced because only a fraction of the original light's intensity is able to pass through the filter.
A polarizer filters unpolarized light by allowing only light waves oscillating in a specific plane to pass through, while blocking light waves oscillating in other planes. It aligns the electric field vectors of the light waves, resulting in linearly polarized light.
Malus's Law is a formula that describes how the intensity of polarized light changes when it passes through a polarizer. In the context of mastering physics, understanding Malus's Law is important for predicting how the polarization of light will be affected by different polarizing filters.
After randomly polarized light passes through a polarizer, it becomes linearly polarized with its electric field oscillating in a specific direction determined by the polarizer's orientation. The intensity of the light decreases due to blocking of the component of light vibrating in a direction perpendicular to the polarizer's transmission axis.
The Malus' law states that the intensity of the polarized light transmitted through the analyser varies as the square of the cosine of the angle between the plane of transmission of the analyser and the plane of the polarizer. Mathematically, it would be: I ∞ cos2θ or I = I0 x cos2θ.

To begin, the correct term is "crossed" polarizer, not cross. The way that a crossed polarizer works is that it contains two polarizers, the first selects a plane of polarized light from an unpolarized light source (containing many oscillations, or planes). The second polarizer than absorbs that plane of polarized light that made it past the first, as it selects a plane of polarized light that is not the one let through the first.

If light passes first thorugh a vertical polarization filter, then through a horizontal polarization filter, hardly any light would get through at all.

A polarizer works by allowing only light waves that are aligned in a specific direction to pass through, while blocking light waves that are oriented differently. This filtering process helps to reduce glare and improve visibility by selectively allowing certain light waves to pass through.
