Question
Explain why (or how):
(e) The shape of a pulse gets distorted during propagation in a dispersive medium.
Solution
A sound pulse is a combination of waves of different wavelength.
As waves of different λ travel in a dispersive medium with different velocities, therefore, the shape of the pulse gets distorted.
