Answer:
Transverse and longitudinal waves
Step-by-step explanation:
In both transverse and longitudinal waves, the particles are displaced from one another. In case of transverse waves the particles are displaced perpendicularly to the wave direction while in case of longitudinal waves the particles are displaced in parallel direction as compared to the direction of wave.
The speed of these waves is not equal to the speed of the particles It is so because wave speed is the speed of disturbance travelling through the wave particles while speed of the particle is the speed with which they travel
