Study Notes

Planck's Constant

  • Named after Max Planck, a founder of quantum mechanics.
  • Represented by the symbol h.
  • It is a fundamental constant of nature that relates a photon's energy to its frequency.

Formula

  • The formula to determine Planck's Constant is:
  • E = hf
  • Where E = energy of the photon
  • h = Planck's constant = 6.626 x 10-34 J * s
  • f = frequency of the photon

Quantum Mechanics

  • In quantum mechanics, energy, momentum, and angular momentum are quantized
  • This means their values are integer multiples of Planck's constant.
  • E = n h f
  • Where n is an integer (1, 2, 3,...)

h-bar

  • Planck's constant is often used in the form ħ (h-bar).
  • h-bar is Planck's constant divided by 2π:
  • ħ = h / 2π = 1.054 x 10-34 J * s

Dimensions

  • Planck's constant has dimensions of energy multiplied by time, also known as action.

Applications

  • It is used in quantum mechanics, statistical mechanics, and thermodynamics.
