Across
- 4. number of cycles per second
- 7. increased density of longitudinal waves
- 8. able to measure and scan blood
- 9. reduced density of longitudinal mechanical waves
- 10. the measured time of 1 wavelength
- 11. measured from peak to peak of a wave
Down
- 1. type of sound wave that requires a medium
- 2. perpendicular to the wave propagation direction
- 3. mass divided by volume =
- 5. waves along the same wave propagation direction
- 6. probe type primarily used in cardiac ultrasound
