A loudspeaker emits a sound wave that propagates through the air.
Which row in the table correctly identifies whether there is a net transfer of matter (the air molecules) and describes the direction of the air molecules' oscillation relative to the direction of energy propagation?
| Net transfer of matter? | Direction of particle oscillation relative to propagation? | |
|---|---|---|
| A | Yes | Parallel |
| B | Yes | Perpendicular |
| C | No | Parallel |
| D | No | Perpendicular |
