Question

How we get dimensional formula of wave amplitude?

Answer 1

The amplitude of wave is defined as the maximum displacement of any point from its rest or equilibrium position on a wave.

Mathematically,

Amplitude of wave = Maximum displacement.

Dimensional formula of displacement = M0L1T0

Putting this value in the above equation we get,

Dimensional Formula of Amplitude of Wave = M0L1T0.
SI unit of Amplitude of Wave is metre(m).

Formulas for area and volume are based on lengths. For example, the area of a circle equals n times the square of the length of its radius, and the volume of a rectangular box is the product of its three linear dimensions: length, width, and height.

Amplitude = Max Displacement
