1: Two basic types of waves. (a)Longitudinal wave, where the oscillatory motion of the particles is in the same direction as that of the wave. (b) Transverse wave, where the oscillatory motion of the particles is perpendicular to that of the wave. The speed of the wave is the distance...
The wave which transmits energy in all directions is called a three-dimensional wave. Sound waves, light waves, radio waves, etc., are three-dimensional waves. On the basis of characteristics of particle vibration: If the particles of a medium vibrate simple harmonically, the corresponding wave...

propagation of wave/energy. In other words, when the energy particles and the wave particles form a perpendicular angle to each other, then it is called a transverse wave. One of the best examples of transverse waves is radio waves, microwaves, ocean waves, wiggling string and polarized waves...
