Across
- 4. = The throwing back by a body or surface of light, heat, or sound without absorbing it.
- 6. spectrum wavelengths or frequencies over electromagnet
- 8. movement caused within a fluid by the tendency of hotter
- 10. = A thing or substance used for insulation, in particular.
Down
- 1. The maximum extent of a vibration or oscillation, measured from the position of equilibrium.
- 2. = A device that generates an intense beam of coherent monochromatic light (or other electromagnetic radiation) by stimulated emission of photons from excited atoms or molecules. Lasers are used in drilling and cutting, alignment and guidance, and in surgery; the optical properties are exploited in holography, reading bar codes, and in recording and playing compact discs.
- 3. = The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
- 5. = The speed of something in a given direction.
- 7. A vehicle's capacity to gain speed within a short time
- 9. = The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.
