Answer 1

A photodiode is used in the detection of both visible and invisible light.

Option (d) is correct.

Explanation:

• A photodiode is a semiconductor device that is used to detect light.
• In order to detect light, a photodiode is exposed to a photon of light and it generates a potential difference upon exposure.
• It also changes its electrical resistance when it comes into contact with a beam of light.
