3. The rate at which someone or something is able to move or operate.
5. having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves. Infrared radiation has a wavelength from about 800 nm to 1 mm, and is emitted particularly by heated objects.
7. having a wavelength shorter than that of the violet end of the visible spectrum but longer than that of X-rays.
9. Strength or energy as an attribute of physical action or movement.
10. A disturbance in a medium that carries energy without a net movement of particles.
11. Reduction in speed or rate.
12. A point on a wave with the maximum value or upward displacement within a cycle.

1. Increase in the rate or speed of something.
4. An amount of space between two things or people.
6. High energy electromagnetic waves
8. The rate at which something occurs or is repeated over a particular period of time.
