A plane progressive harmonic wave is represented by the equation

where is the displacement in meters, t is the time in seconds and x is distance from a fixed origin in meters.

Equation of a wave:

A mechanical wave is generated by a source which oscillates simple harmonically.

As the source oscillates the nearby particles of the medium will also oscillate and one by one the particles will oscillate and the energy is carried out. The velocity with which the disturbance caused in the medium (simple harmonic) is transported is called wave velocity.

Let the particle of medium at origin oscillate such that its displacement is given by the equation

Where A is the amplitude and ...
