  4. 100%

Questions & Step-by-Step Solutions

If unpolarized light passes through a polarizer, what fraction of the light intensity is transmitted?
  • Step 1: Understand that unpolarized light consists of waves vibrating in multiple directions.
  • Step 2: Know that a polarizer is a device that only allows light waves vibrating in a specific direction to pass through.
  • Step 3: When unpolarized light hits the polarizer, the polarizer will only allow half of the light intensity to pass through.
  • Step 4: Therefore, the fraction of light intensity transmitted through the polarizer is 50%.
