PH 122 Lecture Notes - Matter Wave, Wave, Photon
Document Summary
This is most clearly shown by the photoelectric effect. All of the wave phenomena we have seen apply to particles as well. Quantum principles are well understood and well accepted. Changing the accelerating voltage changes the current, but only within certain limits. How much it costs to release an electron. Destructive interference occurs where a crest overlaps a trough. Angles (in radians) of bright fringes for double-slit interference with slit spacing d. Particles have a wave nature h p = h mv. Since particles have a wave nature, the possible states are quantized. Photons have a particle nature their energy is quantized. It comes in chunks of a particular size. Confining them restricts them to certain energy states . The energy of a confined particle is quantized. The wave nature of particles leads to quantized energy levels for electrons in atoms.
