What are Waves ?

• A wave can be described as a disturbance that travels through a medium from one location to another location.
• Consider this example the, When a pebble is thrown in a pond, it creates a disturbance and forms ripples which travel together as a front in a straight-line direction, or the waves may be circular waves that originate from the point where the disturbances occurs in the pond.
  

• The highest point on a wave is called the peak. The lowest point is called the trough.
  

• The waves are classified mainly two types that are longitudinal wave and transverse waves.
• The sound waves are good example of longitudinal wave which is travelled medium with the use of force.
• The electromagnetic radiations are transverse waves which also include the light waves.
