waves

1. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position
5. a wave as it passes from one medium to another
6. the number of waves that pass a fixed point in unit time
10. The process of taking nutrients from the digestive system into the blood so they can be used in the body
12. a long depression less steep than a trench.
17. are waves that are created as a result of vibrations between an electric field and a magnetic field
19. is a propagating dynamic disturbance of one or more quantities
20. (light, heat, sound, etc.) to pass through a medium

2. a form of "electromagnetic" radiation
3. is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
4. a form of electromagnetic radiation, similar to visible light
7. refract light inward toward a focal point
8. waves a wave vibrating in the direction of propagation
9. the repetition of a sound caused by reflection of sound waves
11. electromagnetic radiation of the shortest wavelength and highest energy
13. the substance that transfers the energy, or light from one substance to another substance or from one place to another, or from one surface to another
14. The highest surface part of a wave is called the
15. waves a wave whose oscillations are perpendicular to the direction of the wave's advance
16. a long depression less steep than a trench
18. when light bounces off an object
