What is the effect of a polarizer on unpolarized light?

Step 1: Understand what unpolarized light is. Unpolarized light consists of waves that vibrate in many different directions.
Step 2: Know what a polarizer is. A polarizer is a special filter that only allows light waves of a certain direction to pass through.
Step 3: When unpolarized light hits the polarizer, the polarizer only lets through the light waves that are aligned with its orientation.
Step 4: As a result, some of the light is blocked, which decreases the overall intensity of the light that comes out of the polarizer.
Step 5: The light that passes through the polarizer is now polarized, meaning it vibrates in a single direction.
