Photoelectric Equation

Photoelectric Equation

### Formula:

$$h\nu=\phi+KE$$

### Terminologies:

- hν → Energy of incident photon.

- φ → Work function; minimum energy required to remove an electron from a metal surface.

- KE → Kinetic energy of emitted electron.

- Photon → Smallest packet of electromagnetic radiation.

### Usage:

- Used to explain emission of electrons from a metal surface due to radiation.
