Answer 1

Photoelectric effect is a phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined as the ejection of electrons from a metal plate when light falls on it.



IN SIMPLER WORDS:
The photoelectric effect refers to what happens when electrons are emitted from a material that has absorbed electromagnetic radiation. Physicist Albert Einstein was the first to describe the effect fully, and received a Nobel Prize for his work.

Light with energy above a certain point can be used to knock electrons loose, freeing them from a solid metal surface, according to Scientific American. Each particle of light, called a photon, collides with an electron and uses some of its energy to dislodge the electron. The rest of the photon's energy transfers to the free negative charge, called a photoelectron.


UNDERSTAND FROM IMAGE- When a photon (Y) strikes an electron (E), it knocks it loose and creates a photoelectron.

Answer 2

it is the emission of electrons are other free careers when light shines on the material electrons emitted in the manner can be called photoelectrons this phenomenon is, listed in studied in electronic physics.
