Study Notes
- Classical electromagnetic theory could not explain all phenomena related to the interaction of light with matter.
- Planck introduced the theory of light quanta (photons) in 1900 to explain the radiation emitted by a heated body.
- Einstein used the theory of photons to explain the photoelectric effect.
- According to the quantum theory of Planck, light is emitted and absorbed by atoms in a discontinuous manner, with each atom emitting or absorbing a quantum of energy (photon).
- When light falls on matter, atoms absorb the radiation discontinuously, with each atom absorbing a single photon.
- Each photon of light has a specific frequency and energy.
- When light hits metals, it transfers energy from a photon to one of the metal's electrons.
- Electrons interact with photons as if they were particles.
- The theory of photons does not negate the wave nature of light.
- The energy of a photon depends on its frequency, which is a wave property of light.
