Question

Draw displacement distance graph of two waves a and b such that the amplitude of wave a is three time that of wave b

Answer 1

Since displacement distance has no significance, there might be an error in your question but displacement time graph is shown in the attached figure.

Suppose the displacement equation of wave A is,

Y A = a sin ωt

And displacement equation of wave B is

Y B = 3a sin ωt

So the displacement time graph of the two waves is -
