Polarized light.
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.
Malus's Law explains the behavior of light passing through a polarizing filter. It states that the intensity of light transmitted through the filter is proportional to the square of the cosine of the angle between the filter's transmission axis and the light's polarization direction.
When light passes through a polarizing filter, it becomes linearly polarized, meaning its electric field oscillates in a specific direction. This results in the light being blocked or transmitted based on the orientation of the filter and the polarization direction of the light. Polarizing filters are commonly used in photography and displays to reduce glare and enhance contrast.
Light passing through a polarizing filter still exhibits wave properties. The filter affects the orientation of the light wave's electric field, allowing only certain orientations to pass through. This does not change its fundamental nature as a wave.

Polarizing a beam of light is simply accomplished by passing the light through a polarizing filter. The polarizing filter will permit only light of a given polarization (or polarity) to pass through it. There are several different types of polarization, but they affect similar results.
