Across
- 1. one half the full extent of a vibration, oscillation, or wave.
- 5. the speed of something in a given direction.
- 6. a device that generates an intense beam of coherent monochromatic light by stimulated emission of photons from excited atoms or molecules.
- 7. is the transfer of energy in the form of heat or electricity from one atom to another within an object by direct contact.
- 9. the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.
- 10. is defined as the rate of change of velocity.
- 11. the number of crests of a wave that move past a given point in a given unit of time.
Down
- 2. a material or an object that does not easily allow heat, electricity, light, or sound to pass through it.
- 3. spectrum is the range of all types of EM radiation.
- 4. the throwing back by a body or surface of light, heat, or sound without absorbing it.
