| Question | Answer |
| Photoelectric Effect | When electrons are emitted from the surface of a metal due to electromagnetic radiation hitting the metal |
| Photon | Bundle of light energy |
| Energy of a photon | E = hf |
| Einstein's Photoelectric Law | The energy of the fastest electron emitted is the difference between the energy of the photon and the work function of the metal |
| Work function | The energy needed to remove the loosest electron from the surface of a metal |
| Threshold frequency | The minimum frequency needed to cause photoelectric emission |
| Velocity of the emitted electron depends on .. | The frequency of the light wave |
| Number of electrons emitted depends on ... | The intensity of the light |
| Formula for Einstein's Photoelectric Law | hf = ϕ + 1/2(m)(vmax)² |
