Sound Waves and Hearing

4. The number of cycles.
5. The maximum distance that the particle of the wave's medium vibrate from their rest position
9. A wave in which the particles of the medium vibrates parallel to the direction of wave motion.
10. The combination of two or more waves that results in a single wave
13. The time required for corresponding point on consecutive wave to pass a given point.
15. A phenomenon that occurs when two objects naturally vibrate at the same frequency.
16. A wave that requires a medium through which to travel.
18. The speed at which a wave travels
19. The distance from any point on a wave to a corresponding point on the next point
21. The process of using reflected sound waves to find objects

1. A wave consisting of changing electric and magnetic fields.
2. A longitudinal wave that is caused by vibrations and that travels through a material medium.
3. Sound navigation and ranging
6. A unit of frequency equal to one cycle per second.
7. A disturbance that transfers energy from one place to another
8. A physical environment in which phenomena occur.
11. A wave in which the particles of the median move perpendicular to the direction the wave is traveling
12. An observed change in frequency of a wave when the source is moving.
14. A measure of how high or low a sound is perceived to be.
17. The most common unit used to measure loudness
20. A reflected sound wave.
