a) all the particles are vibrating in the same phase

b) amplitude of all the particles is equal

c) particles of the medium executes SHM

d) wave velocity depends upon the nature of the medium

Answer:

The correct options are

b) amplitude of all the particles is equal

c) particles of the medium executes SHM

d) wave velocity depends upon the nature of the medium

Explanation:

During the propagation of a plane progressive mechanical wave, the amplitude of all particles is equal, medium particles execute S.H.M, wave velocity is determined by the medium’s nature, and all particles vibrate in distinct phases.
