what happens when ultrasound meet the boundaries of different materials
- some ultrasound waves are reflected at the boundary
- time taken from wave to leave and return to detector is measured
- the depth of boundary can be determined

what are p waves
longitudinal waves
12 of 22
properties of p waves
- can travel through solid and liquids
- faster than s waves
13 of 22
what are s waves
transverse waves
14 of 22
properties of s waves
- can only pass through solids
- slower than p waves
