Physics Waves

5. the number of waves that pass a fixed point in unit time
6. the way the electric field of the radio wave is oriented
8. the change in frequency of a wave in relation to an observer who is moving
14. the horizontal line in the middle of the wave
15. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave
17. a wave of compression and rarefaction, by which it is propagated in an elastic medium
19. the maximum displacement measured from its equilibrium position
20. occurs when waves bounce back from a surface they cannot pass through

1. an electromagnetic wave which travels through the vacuum of outer space
2. a wave with a repeating continuous pattern which determines its wavelength and frequency
3. when a wave passes from one medium to another and is bent
4. the high point of a transverse wave
6. position of a single sound in the complete range of sound
7. a device to measure the wavelength or the frequency of an electromagnetic or radio signal
9. The time it takes for one wavelength to pass a specified point
10. speed the distance traveled by a given point on the wave in a given interval of time
11. a logarithmic measure of a power or amplitude ratio
12. The amplitude of a sound wave determines its intensity, which in turn is perceived by the ear
13. the spreading of waves around obstacles
16. the minimum or lowest point in a cycle
18. when the amplitude of an object's oscillations is increased by the matching vibrations of another object
