3 cards from this section. Quick, good the night before a test.
What is the photoelectric effect?
Think about the interaction between light and electrons.
Define work function.
Consider this as the barrier for electron release.
What is the photoelectric effect?
What happens to electrons when light hits a metal?
Einstein’s photoelectric equation shows that the maximum kinetic energy of emitted electrons depends on the frequency of light.
Think about how different frequencies might affect energy.
If a metal has a work function of 4.5 eV, what is the threshold frequency for photoelectric emission?
Convert eV to J first before using Planck's constant.
Calculate the de Broglie wavelength of an electron with a momentum of 5 × 10^-24 kg m/s.
Ensure you keep units consistent when substituting values.
