The amplitude of a sound wave can be defined as the loudness or the amount of maximum displacement of vibrating particles of the medium from their mean position when the sound is produced. Figure 4. Amplitude = 16 cm. It is equal to one-half the length of the vibration path. The wave can be described as having a vertical distance of 32 cm from a trough to a crest, a frequency of 2.4 Hz, and a horizontal distance of 48 cm from a crest to the nearest trough. It is measured by the depth from the equilibrium point to the lowest point of a trough or the height from the equilibrium point to the highest point of a crest. They might have the exact same frequency and wavelength, but the amplitudes of the waves can be very different. Determine the amplitude, period, and wavelength of such a wave. the depth from the equilibrium point to the lowest point of a trough. Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. This maximum displacement is measured from the equilibrium position. It is the distance between crest or trough and the mean position of the wave. Waves are generated by vibrating sources, their amplitude being proportional to the amplitude … Amplitude (a) of a wave is how big the wave is or the energy of the wave. The amplitude of a wave is measured as: the height from the equilibrium point to the highest point of a crest or.

Amplitude is the maximum displacement of points on a wave, which you can think of as the degree or intensity of change. See Answer.
