Across
- 4. the energy needed to free the most weakly bound electron from a metal
- 7. if the frequency of the incident radiation is greater than a certain minimum value
- 8. A graph of the intensity of the radiation emitted from an object over a range of frequencies
Down
- 1. The emission of electrons when electromagnetic radiation falls on an object
- 2. visible light and other forms of electromagnetic radiation consists of discrete,quantized bundles of energy
- 3. only exists in bundles of specific amounts
- 5. the shift in the energy of scattered photons
- 6. electrons eject from the cathode
