- 3. A particle of electromagnetic radiation with no mass that carries a quantum of energy
- 11. The height of a wave from the origin to a crest, or from the origin to trough
- 12. spectra includes all forms electromagnetic radiation; the types of radiation differ in their frequencies and wavelengths
- 14. The capacity to do work or produce heat; exists as potential energy, which is stored in an object due to its composition or position, and kinetic energy, which is the energy of motion
- 15. The number of waves that pass a given point per second

- 1. state The lowest allowable energy state of an atom
- 2. effect A phenomenon in which photoelectrons are emitted from a metal's surface when light of a certain frequency shines on the surface
- 4. The minimum amount of energy that can be gained or lost by an atom
- 5. orbital A three-dimensional region around the nucleus of an atom that describes an electron's probably location

- 7. sublevel The energy levels contained within a principal energy level
- 8. The shortest distance between equivalent points on a continuous wave; is usually expressed in meter, centimeters, or nanometer
- 9. A physical phenomenon characterized by its frequency, and amplitude
- 10. emission spectrum A set of frequencies of electromagnetic waves given off by atoms of an element; consist of a series of fine lines of individual colors
- 13. state State of a system with energy higher of that of the ground state
