Physics Terminology

6. This is one of the acoustic variables. Any mechanical system produces heat, as the wave propagates it losses energy to the surrounding medium.
8. Sound will travel through this in a medium when the line segments are farther apart, meaning the molecules are farther apart.
10. This can be described as a longitudinal mechanical wave.
11. Sound travels through this in a medium, specifically when there is a high particle density, such as in muscle.
13. The molecules move in the same direction as the wave.
14. This can be defined as the maximum variation of a variable from its mean value.
17. This type of wave will propagate in a medium, or a vacuum.
19. This type of wave requires a medium to propagate.
21. As this wave characteristic increases, frequency decreases and vice versa.

1. This wave measurement depends on the physical properties of the medium and is not dependant on the frequency of the sound wave
2. Frequency and time can be characterized as ___________ of each other.
3. The length of space that one cycle takes up.
4. This is one of the acoustic variables that is defined as a concentration of force, or force per area, in the compression phase of propagation this increases, and in rarefaction this decreases
5. This can be defined as the time it takes for the wave to transition from compression through rarefaction and back to compression.
7. Water, sound, light, x-rays, and radio signals all travel in the form of ________.
9. This wave characteristic is measured in (Hertz/Hz)
12. Amplitude is determined by measuring the difference between this and the maximum.
15. The formula for this measurement is mass/volume.
16. The material through which the sound wave is travelling.
18. This type of wave propagates by particle motion that is perpendicular or otherwise known as _________ to the wave propagation direction.
20. In this type of drawing, the measurement of time and of distance appear as the same characteristic in the drawing.
