Electrons, waves, and photons: Quantum physics Flashcards
what are photons
a photon is the
particle-like manifestation of light
what is energy of a photon proportional to
frequency
what is another way to describe the energy of the photon
eV
what is the photoelectric effect
where shining high intensity light onto the surface of a metal in which electrons are emitted
what features of the photoelectric effect cant be explained if a light is a wave
if light was a wave, then energy of the electrons released would increase with the rising intensity but that is nto the case as it is only the frequency of electrons that change the energy
how many photons does each photoelectron absorb prior to emisiion
1
what is the name given to the minimum energy required for a photoelectron to leave the surface of a metal
work function
