Question

How to draw a displacement-time graph from a displacement-distance graph ?

Answer 1

We cannot draw the other when either one is given as the informations showed by them are two different things.
Displacement-distanc e graph shows the displacements of particles of a wave from their equilibrium position at a certain time, it can show the amplitude and wavelength of the wave.
Displacement-time graph shows the displacement of a particular particle from its equilibrium position with time, it shows only amplitude and period(or frequency) of the wave.
However, if you have a displacement-distanc e graph and the period of the wave,then you can draw a displacement-time graph.Or you have a displacement-time graph and the wavelength of the wave,you can draw a displacement-distanc e graph.
