A divice for measuring a response of photo cell is called....
​

Answer 1

⚡☺️Hey Buddy!!☺️⚡

==>Photocell is a device which converts light energy into electrical energy. In photocell concave metallic cathode absorbs photons from incident light waves and emits electron from the metal surface towards anode.

In other words, it absorbs light and produces a stream of electrons..

Answer 2

Answer:

A photocell response measurement device is called a photoelectric cell.

Explanation:

• The Photoelectric device is a device that provides an electrical signal in response to visible, infrared, or ultraviolet radiation.
• They are often used in sensory systems with changes in light received or transmitted.

A photoelectric cell is a sensitive electrical device in the event of radiation, especially visible light, which is used to generate or control the output of electrical energy.

Photocells are protection that changes their negative value depending on how much light shines on a squiggly surface.

So, a photocell response measurement device is called a photoelectric cell.
