QUANTUM THEORY & PHOTONS
• The Photon
• 𝐸𝑃ℎ𝑜𝑡𝑜𝑛 = ℎ𝑓
• Compton Effect
• Matter Waves
• λ =ℎ
𝑝

THE PHOTON
• Light is Electromagnetic Energy
• It exists in small bundles or packets
• Photon - Photons
• Quantum - Quanta

THE PHOTON
𝐸𝑝ℎ𝑜𝑡𝑜𝑛 = ℎ𝑓
• 𝐸𝑝ℎ𝑜𝑡𝑜𝑛 = the energy of a photon (Joules)
• ℎ = Planck’s Constant
• 𝑓 = the frequency of the photon (Hertz)

COMPTON EFFECT
• Waves ACT like Particles
• Bombarded Graphite with X-Rays
• Scattered X-Rays and Electrons
• Scattered X-Rays were of a Lower Frequency
-
MATTER WAVES
• Louis De Broglie
• Particles ACT like Waves
• Electrons and Neutrons
• Diffraction Patterns
-
CONSERVATION
• Particles ACT like Waves
• Waves ACT like Particles
• Momentum is
Conserved
• Energy is Conserved
λ =ℎ
𝑝
• λ = wavelength (meters)
• ℎ = Planck’s Constant
• 𝑝 = momentum (𝑘𝑔 ∙ Τ𝑚 𝑠)
