Across
- 3. the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.
- 7. the rate at which something occurs or is repeated over a particular period of time or in a given sample.
- 9. the maximum extent of a vibration or oscillation, measured from the position of equilibrium
- 10. spectrum the range of wavelengths or frequencies over which electromagnetic radiation extends
- 11. the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat
Down
- 1. the speed of something in a given direction.
- 2. a device that generates an intense beam of coherent monochromatic light (or other electromagnetic radiation
- 4. a substance that does not readily allow the passage of heat or sound.
- 5. the process by which sound waves travel through a medium
- 6. increase in the rate or speed of something
- 8. the throwing back by a body or surface of light, heat, or sound without absorbing it.
