The position of particles of the medium can be mathematically modeled as wave functions, which can be used to find the position, velocity, and acceleration of the particles of the medium of the wave at any time.
Pulses
A pulse can be described as wave consisting of a single disturbance that moves through the medium with a constant amplitude. The
