Introduction to Waves

1. The type of ultrasound used to detect and measure blood flow in vessels
4. A wave classification denoting a medium is not required for wave propagation
6. The time taken to complete one cycle (compression to rarefaction back to compression)
7. A mechanical, longitudinal wave type used in the field of ultrasound
9. low particle density in a longitudinal wave
11. The rate (m/sec) at which a wave travels through a medium
14. Transfers of energy that propagate through a medium
16. The number of cycles per second
18. The motion of particles perpendicular to the wave propagation direction
19. Leading to wave cancellation, the maxima of one wave aligns with the minima of another wave
20. The construction of a larger wave when the minima and maxima of two waves are aligned

2. A partial construction of a bigger wave due to the fact that the two consecutive waves are not completely in and out of phase
3. The effect by which a transducer converts energy into another form
5. A wave classification denoting a medium is required for wave propagation
8. The distance between one peak compression to the subsequent peak compression
10. The maximum variation of a variable from the mean value
12. Pressure, density, particle motion and temperature are
13. high particle density in a longitudinal wave
15. Particles' compressions and rarefactions lead to particle motion wherein the wave direction and propagation direction are the same
17. Known as the time between when the pulse was created to when the pulse was received
