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.
