Question

The maximum displacement of a wave on either side of its mean position is called ……….

Answer 1

Hint: The amount of energy carried by a wave is related to the amplitude of the wave.

Complete step by step solution:
Let us first understand some basic terms which defines a wave:
crest: It is the point on the wave with maximum value on the positive side of the wave or we can say that crest is the point of maximum value above the mean line of the wave.

Trough: It is the point on the wave with minimum value on the negative side of the wave or it can also be stated as the point of minimum value below the mean line of the wave.

Amplitude: Amplitude of a wave is defined as the maximum displacement of the wave on any of the side of its mean position.

By clearly understanding the definition of amplitude we can say that the final answer is Amplitude.

Note: Do not get confused in defining the side as amplitude for a wave is equal on both the sides.
