Answer:
Step-by-step explanation:
1. A Transverse wave is motion in which all points on a wave move or swing back and forth at a regular speed along paths at right angles to the direction of the wave's advance and an example is ripples on the surface of water. A Longitudinal wave is a wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave and an example ultrasound waves.
2. A motion wave is the transfer of energy and momentum from one point of the medium to another point of the medium without actual transport of matter between two points.
3. f is force and 人 is wave length
