Across
  1. 2. A term describing a structure or tissue that produces less echoes on an image compared to another
  2. 4. Typically measured in seconds
  3. 6. Example of a mechanical longitudinal wave
  4. 7. A term describing a structure or tissue that produces more echoes on an image compared to another
  5. 11. How many times an event occurs per time
  6. 13. Unit commonly used to measure pressure
  7. 15. Calculated as Mass (kg) per volume (m3)
  8. 17. The rate at which the wave propagates through a medium
  9. 21. A term that describes the absence of echoes
  10. 22. The speed of sound through this medium is 1540 m/s
Down
  1. 1. This wave type propagates by particle compression and refraction that results in particle motion parallel to the wave direction
  2. 3. In the compression phase of propagation this increases
  3. 5. This wave type will work in a medium or a vacuum
  4. 8. As a wave travels through a medium some of the energy is loss to this
  5. 9. Pressure, density, temperature, and particle motion are all examples of
  6. 10. A tissue or structure that reflects sound waves would be considered
  7. 12. The speed of sound through this medium is 1484 m/s
  8. 14. A wavelength defines the completion of one of these
  9. 16. This wave type needs a medium
  10. 18. This effect is the principle of converting energy by applying pressure to a crystal
  11. 19. The particle motion of this wave is perpendicular to the propagation direction of the wave
  12. 20. Measurement of wave frequency
