However, frequency change leads to a change in energy. Suppose a wave generator is used to produce several waves within a rope of a measurable tension. If both amplitude and frequency are high, then even the energy carried by the wave will be more. Wave amplitude is determined by the energy of the disturbance that causes the wave. The frequency of sound can affect the perceived loudness, where amplitude is held constant. How is the angular frequency related to the period? Why does a node occur in a standing wave? No real wave is perfectly linear. Does pulse width affect the speed of the wave? If you are considering sound waves, their amplitude determines how loud the sound is. Increasing the tension on a string increases the speed of a wave, which increases the frequency (for a given length). The amplitude of a wave does not affect the speed at which the wave travels. When watching ocean waves approaching shallower water, this effect is very noticeable. A doubling of the wavelength results in a halving of the frequency; yet the wave speed is not changed. Also, the amplitude can affect one's sensitivity to detecting small changes in pitch. The waves energy can go up or down.
