波粒二象性 (Wave-Particle Duality)

Particulate Nature

  1. Maximum kinetic energy of a phototelectron depends on the frequency of the photon.

    • 每次吸收的能量是定值

  2. Maximum kinetic energy of a phototelectron is independent of the intensity.

    • 能量与光强无关

  3. Threshold frequency of the emission of phototelectrons, below which photoemission cannot be emitted.

    • 能量最小值，不能发射光子

  4. Rate of emission of phototelectrons is pro

  1. Gradient = \(h\) Plank constant
  2. X-intercept = \(f_0\) minimum frequency
  3. Y-intercept = \(E_{min}\) = \(\phi\) minimum energy

定义 (Definitions)

  1. \(E_{min}\), \(\phi\): Minimum energy for an electron to be emitted from the surface of a metal.
  2. \(h\): Planck's constant.
