Answer:
Amplitude
Explanation:
Amplitude is defined as the maximum displacement of a wave. Displacement is similar to distance but it is a vector quantity( that is it measures both magnitude and direction)
It is usually measured by the different between the lowest(rest) point and the highest(crest) point.
The energy of a wave is determined by the amplitude. The higher/larger the amplitude , the higher the energy of the wave. It is measured in meters.
