Questions & Step-by-Step Solutions

What happens to the polarization of light when it passes through a polarizer at an angle of 45 degrees?
  • Step 1: Understand that light can vibrate in many directions. This is called polarization.
  • Step 2: A polarizer is a special filter that only allows light vibrating in a certain direction to pass through.
  • Step 3: When unpolarized light (light with vibrations in all directions) hits a polarizer, it gets filtered.
  • Step 4: If the polarizer is at a 45-degree angle, it allows some of the light to pass through, but not all of it.
  • Step 5: The light that passes through becomes partially polarized, meaning it has some vibrations in the direction of the polarizer.
