| 11. | The photoelectron spectrum of dihydrogen shows a single set of multiplets between 16 and 18 eV ( electron volts ).
|
| 12. | HI regions effectively absorb photons that are energetic enough to ionize hydrogen, which requires an energy of 13.6 electron volts.
|
| 13. | After the collision, the electron inside occupies a higher energy level with 4.9 electron volts ( eV ) more energy.
|
| 14. | Electrons in a television set are accelerated by a picture tube to an energy of about 50, 000 electron volts.
|
| 15. | The variable measured is most often the light's reciprocal centimeters or electron volts, which has a reciprocal relationship to wavelength.
|
| 16. | The binding energy of the 1s orbital of an atom with Z protons is approximately 13.6 * Z electron volts.
|
| 17. | The energy released by this reaction is in millions of electron volts, which is actually only a tiny amount of energy.
|
| 18. | :: : : The energy per atom would be at least a few thousand electron volts, so it would probably be nuclear.
|
| 19. | To treat tumors at greater depths, the proton accelerator must produce a beam with higher energy, typically given in eV or electron volts.
|
| 20. | The immediate energy release per atom is about 180 million electron volts ( MeV ); i . e ., 74 TJ / kg.
