Question

What is the phenomenon of photodetection?

Answer 1

Photosensors or photodetectors are sensors of light or other electromagnetic energy.[1] A photo detector has a p–n junctionthat converts light photons into current. The junction is covered by an illumination window, usually having an anti-reflective coating. The absorbed photons make electron-hole pairs in the depletion region. Photodiodes and photo transistors are a few examples of photo detectors. Solar cells convert some of the light energy absorbed into electrical energy. Photodetectors are often used in mobiles to adjust LCD brightness display.

Answer 2

Explanation:

natural phenomenon - all phenomena that are not artificial. phenomenon - any state or process known through the senses rather than by intuition or reasoning. chemical phenomenon - any natural phenomenon involving chemistry (as changes to atoms or molecules)
