quantum concepts
Quantum Concepts
  • Bohr Atom
  • Light Quanta (particle-like waves)
  • Wave-like properties of particles
  • Wave-Particle Duality
bohr model for hydrogen atom
Bohr model forHydrogen atom
  • Electron (-q) rev. around proton (+q)
  • Coulomb force, F = q2/4peor2, q = 1.6E-19 Coul, eo=8.854E-14Fd/cm
  • Quantization L = mvr = nh/2p, h =6.625E-34J-sec

Bohr model for the H atom (cont.)
  • En= -(mq4)/[8eo2h2n2] ~ -13.6 eV/n2
  • rn= [n2eoh2]/[pmq2] ~ 0.05 nm = 1/2 Ao

for n=1, ground state

Energy Quanta for Light
  • Photoelectric Effect:
  • Tmax is the energy of the electron emitted from a material surface when light of frequency f is incident.
  • fo, frequency for zero KE, mat’l spec.
  • h is Planck’s (a universal) constant h = 6.625E-34 J-sec
