Across
- 4. Light strikes a metal can cause the emission of an electron.
- 5. The X-ray spectrum emitted by the anode consists of _______ and a continuous spectrum of radiation.
- 6. The maximum wavelength above which no leakage current or photoemission occur since the photon energy is now less than the gap between the valence and the conduction band.
- 8. The minimum quantity of energy which is required to remove an electron from the surface of a metal to infinity.
- 9. Dependent or independent? The kinetic energy of photoelectrons and the intensity of incident radiation.
- 11. a continuous spectrum of X-ray radiation caused by the violent deceleration of charges of the electrons as they hit the anode.
- 12. ___________ of an ejected electron equals the photon energy minus the binding energy BE of the electron in the specific material.
- 13. A model that characterizes light as having particle properties: momentum and energy, and as having wave properties: wavelength and frequency.
Down
- 1. A unit of energy that is equivalent to the amount of kinetic energy gained or lost by a single accelerating from rest through an electric potential difference of one in vacuum.
- 2. The minimum frequency of the incident radiation below which photoelectric emission or emission of electrons is not possible.
- 3. The minimum electric potential required to be applied to a charged particle in motion, i.e. with kinetic energy, to completely stop it from moving.
- 7. In the equation E=hf, what does the f represent?
- 10. Shows wave-like behavior.
