Explanation:

A wave which travels continuously in a medium in the same direction without the change in its amplitude is called a travelling wave or a progressive wave.During propagation of a plane progressive mechanical wave all the particles are vibrating with different phases.

Hence the statement given in option 1 is incorrect.
