Answer:
a. sinusoidal wave
Explanation:
As we know that the medium particle will move in SHM when disturbance travel through the medium
Here the wave propagation through many ways are possible through the medium
When medium particles performs SHM then in that case the wave equation is given as
[tex]y = A sin(\omega t + k x + \phi_0)[/tex]
so we have above equation of wave must be sinusoidal equations
so correct answer will be
a. sinusoidal wave
