Medical imaging techniques often employ different types of waves to investigate internal structures. Which row, A, B, C or D, correctly describes the properties of an ultrasound wave?
| Wave type | Can be polarised? | Propagation in a vacuum | |
|---|---|---|---|
| A | Transverse | Yes | Can propagate |
| B | Longitudinal | Yes | Cannot propagate |
| C | Longitudinal | No | Cannot propagate |
| D | Transverse | No | Can propagate |
