The maximum displacement of a wave from its resting position. Higher amplitude means higher energy.
Amplitude is a measure of how large the oscillations or vibrations of a wave are, and it is directly related to the energy of the wave. The maximum displacement from the resting position is known as the peak amplitude. The higher the amplitude of a wave, the more energy it carries and the greater its impact. Amplitude is measured in units such as meters, volts, or decibels, depending on the type of wave being considered.
In the context of sound waves, for example, higher amplitude means louder sound. In the context of light waves, higher amplitude means greater brightness. In the context of seismic waves, higher amplitude means more intense shaking.
Overall, amplitude is an important factor in determining the characteristics and effects of a wave, and understanding it can help in analyzing and predicting the behavior of various wave phenomena.
