- 3. the internal energy of an object due to the kinetic energy of its atoms and/or molecules. The atoms and/or molecules of a hotter object have greater kinetic energy than those of a colder one, in the form of vibrational, rotational, or, in the case of a gas, translational motion.
- 5. the process by which one thing absorbs or is absorbed by another.
- 8. one of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity and that include radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
- 10. the throwing back by a body or surface of light, heat, or sound without absorbing it.
- 11. are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz (Hz). ... Naturally occurring radio waves are emitted by lightning and astronomical objects.
- 13. is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission the material is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.
- 14. Ultraviolet radiation. Invisible rays that are part of the energy that comes from the sun, can burn the skin, and cause skin cancer. ... UVC is the most dangerous type of ultraviolet light but cannot penetrate earth's protective ozone layer.
- 15. the strength and vitality required for sustained physical or mental activity.

- 1. change the form, character, or function of something.
- 2. is a measurement that tells you how Much Light the color reflects.
- 4. the action or process of transmitting something or the state of being transmitted.
- 6. no light can pass through-
- 7. the natural agent that stimulates sight and makes things visible.
- 9. Some light can pass through
- 12. all light can pass through-
