Particle Nature of EM Radiation

• EM radiation has a particle nature when interacting with matter
• According to the particle nature:

  • EM radiation consists of a stream of particles
  • They are called PHOTONS
  • A photon is a packet of energy found in light
• The energy (E) of a photon of EM radiation is Directly Proportional to its frequency
• E=hf (energy=frequency x wavelength)
• 1. E=hc/λ
  2. h=(6,63) (10-34) J.s is Planck's constant
