For detecting light intensity we use

For detecting light intensity we use
  1. photodiode in reverse bias.
  2. photodiode in forwarded bias.
  3. LED in reverse bias.
  4. LED in forward bias.

Solution

The device which is used for detecting light intensity is Photodiode. Photodiode is a type of PN junction that generates current when exposed to light. It operates in reverse biased mode and converts light energy into electrical energy and is also known as a photodetector or a photosensor. *
