However, for small amplitudes (typically around a few degrees), the amplitude has no effect on the period of a pendulum. Larger the amplitude, the higher the energy. The speed of a wave is only altered by alterations in the properties of the medium through which it travels. This means it is the distance from the center line drawn through a wave and either the peak or the trough of the wave. A very large amplitude can increase the speed of sound in a medium. If it takes 0.150 s to travel to the object and back, then it takes 0.075 s to travel the one-way distance to the object. Loudness: It is a feeling of how strong a sound wave is at any place.
