The Photoelectric Effect The emmision of electrons from a metal when electromagnetic radiation of
high enough frequency falls on the surface.
Threshold Frequency (f₀)...
The Photoelectric Effect ✅The emmision of electrons from a metal when electromagnetic radiation of
high enough frequency falls on the surface.
Threshold Frequency (f₀) ✅Minimum frequency of light needed to eject electrons fromt he surface of
the metal
Classical Theory ✅Light acts as a wave and the energy of a wave depends on its amplitude (intensity)
not its frequency.
Work Function ✅E = hf
ɸ = hf₀
Einstein's Photoelectric Effect Equation ✅Eᵀ = Eᵀ
hf = ɸ + Eᴹªˣ
hf = hf₀ + Eᴹªˣ
De Broglie Hypothesis ✅All particles can behave like waves whose wavelength is given by ƛ = h/p (h:
Planck's constant, p: momentum of particle)
Wave Matter ✅All moving particles have a "matter wave" associated with them whose wavelength is
the De Broglie wavelength.
