Mechanical waves are waves where the wave requires a means to propagate.
- Waves strap: strap means.
- Water waves: the water supply.
- Sound waves: a means solid, Liquid, Air.
- The wave springs: a spring means.
- Stationary waves are the wave propagation and vibration directions perpendicular to each other.
Example: a wave of water and rope.
- Tongitudinal wave is a wave propagation and vibration directions coincide.
Example: Wave Spring and sound wave
