fixed and the damping is reduced to zero, the wave oscillates with gradually increasing amplitude above the natural frequency of the generating medium.
When set on the loose end, with the initial default conditions kept constant, the wave gradually decays in an exponential manner and when the damping is offset the wave oscillates with almost equal amplitude. However setting no end on, with zero damping a wave with crests of equal amplitude is generated and a smooth wave flow is observed. Additionally, when the damping is set at zero and at loose end, the amplitude of the wave increases gradually and the wave interferes destructively and starts over and over again. A similar condition is experienced when it is set at the fixed end with zero amplitude, in which case, the reflected part of the wave interferes destructively constantly. The natural phenomena like tides in oceans, earthquakes and waves on a string are examples
The term standing wave is used to denote the resonant mode of the vibrating string or the simulation used in this experiment. The resonance in this simulation is created by constructive interference of two waves which travel in opposite directions in the same medium creating a simple harmonic oscillator. Diagrams 1 through 4 in the inserted pictures above show how the wave transits from one stage to another and eventually returns to the initial position showing a simple harmonic
