Physics 12

2. The change in pitch perceived when there is relative motion between an observer and a source of a wave
4. slower than Mach 1
7. The distance between trough to trough, or crest to crest
10. if a sound wave has a frequency lower than the human audible range it is referred to as
12. has an antinode at one end and a node at the other end
13. unit to measure intensity of sound
15. Number of cycles in a wave per second
17. if a sound wave has a frequency exceeding the human audible range it is referred to as
18. the rate at which energy is transferred through a medium (per unit area)
19. integral multiples of the fundamental frequencies
20. a loud explosive noise caused by the shock wave when something travels faster than the speed of sound

1. wave that has a velocity faster than that of sound
3. the loudest and lowest frequency of vibration of a standing wave
5. pulsation in loudness heard when two similar frequencies sound at the same time
6. Wave Continuous oscillation of a wave
8. the speed of sound at 0 degrees Celsius
9. has antinodes at both ends
11. The frequency perceived by humans
14. depends on the amplitude of waves
16. blending or mixture of harmonics
