Give answer to this question ❓
@pwncertwallah

Answers of the question 👇👇

Photoelectric Effect

It is the phenomenon where electrons are emitted from a metal surface when light of suitable frequency falls on it.

---

Experimental results unexplained by classical physics

Existence of a threshold frequency below which no electrons are emitted, no matter how intense the light is.

Instantaneous emission of electrons as soon as light of threshold frequency shines.

Kinetic energy of emitted electrons depends only on the frequency of light, not on its intensity.

---

Explanation by quantum theory

Light consists of energy packets called photons, each with energy .

When a photon hits the metal, it transfers its energy to an electron.

If is greater than the work function (minimum energy needed to free the electron), the electron is emitted with:
K.E. = hv - Φ

🌠 Hold your dream tight — don’t let go!
