Across
- 2. the specific wavelengths of electromagnetic radiation emitted by the electrons of atoms or molecules as those electrons return to a lower and more stable energy state
- 5. a form of energy that exhibits wavelike behavior as it travels through space; part of the electromagnetic spectrum
- 6. the distance between two adjacent crests or troughs of a wave
- 8. the distribution of energy in wavelengths within a system
- 10. an electron at the lowest possible energy for an atom
- 11. electrons that momentarily occupy an energy state that is higher than at the ground state
- 13. the number of wave cycles that pass a given point per unit of time
- 14. the behavior of a wave as it bends around a sharp edge; occurs when a wave passes through a single narrow slit or multiple narrow slits
- 15. an elementary particle that is the smallest possible amount of light and all other forms of electromagnetic radiation that can interact with anything
Down
- 1. a continuum of all electromagnetic waves arranged according to frequency and wavelength
- 3. the height of a wave from origin to the crest or trough
- 4. discrete regions around the nucleus where electrons can exist
- 7. the combination of two or more of the same type of wave
- 9. the observation that when certain wavelengths of light strike a piece of metal, electrons are emitted, potentially creating an electric current
- 12. a device that measures the properties of the different wavelengths of electromagnetic radiation coming from a single source
