Module 4 – Quantum
Physics
, The Particle Nature of Light
• Light interacts with matter as a particle.
• These particles are called PHOTONS.
• A photon is a "packet of energy" of value E specific to the frequency of the lig
• The energy of a photon is equal to:
E= Energy of a photon = frequency x Plan
hf constant
hc Planck's constant x speed of light i
E= Energy of a vacuum
λ photon = wavelength
• Planck's constant, h = 6.63 x 10-34 Js
The Einstein relation links particle and wave properties of light.
