What you learn in Theory:
Radiation energy is built up of discrete units called quanta of energy of radiation.
What you learn in Practice:
If this quantum of energy absorbed exceeds the minimum energy needed for the electron to escape from the metal surface (work function ?0), the electron is emitted with maximum kinetic energy.
