Question

Draw displacement-time graph of a wave and show on it the amplitude and time period of wave.

WhatsApp

Answer

The figure below shows the variation of displacement with time for a particle of the medium at a given position, when a wave propagates through the medium. It is called displacement-time graph.

The amplitude is represented by the letter a and the time period is represented by the letter T.
