Analytical cookies are used to understand how visitors interact with the website. What is the difference between amplitude and frequency? For a high amplitude to occur, the length of the amplitude must be to its maximum, creating a long path to help the wave carry more energy and transfer more particles that will lead to more propagation in the medium and help increase the amplitude. It also does not affect wave speed. Factors not affecting the speed of sound are pressure, amplitude, wavelength and frequency of the sound wave. The amount of energy needed by the source to produce the sound. If a body attached to a spring is displaced from its equilibrium position, the spring exerts a restoring forceon it, which tends to restore the object to the equilibrium position.
