Hey Guys...... ☑☑☑☑☑☑

WhAt Is PhoTo Electric EffeCt.........❓❓❓❓❓❓❓​

Answer 1

Explanation:

The photoelectric effect is the emission of electrons or other free carriers when light hits a material. Electrons emitted in this manner can be called photoelectrons. This phenomenon is commonly studied in electronic physics and in fields of chemistry such as quantum chemistry and electrochemistry.

Answer 2

Answer:

The emission of electrons from a metal surface when light is incident on it is known as photoelectric effect.

There's a minimum energy which is required for the emission of electrons corresponding to which that frequency is known as the threshold frequency and that maximum wavelength is known as the critical or stoppage wavelength.

Also, in the modern research it has been found out that not only electrons can be ejected, but more fundamental particles can also be ejected.

It was Professor Einstein who won the Nobel Prize in Physics in 1902 for his fundamental work in development of photo electric effect.

Though, many believe it was before Einstein. that other amazing scientists had already discovered and developed a well enough theory over Photo electric effect.

Like pair scientists like

Lenard and Hawks

Or Geiger and Marsden.

Hope this helps you !
