A transverse wave travels along the Z-axis. The particles of the medium must move:
1. | along the Z-axis | 2. | along the X-axis |
3. | along the Y-axis | 4. | in the X-Y plane |
A wave moving in a gas:
1. | must be longitudinal | 2. | may be longitudinal |
3. | must be transverse | 4. | may be transverse |
1. | Mechanical transverse waves can propagate through all mediums. |
2. | Longitudinal waves can propagate through solids only. |
3. | Mechanical transverse waves can propagate through solids only. |
4. | Longitudinal waves can propagate through vacuum. |
