Question

During propagation of a plane progressive mechanical wave :

• A. all the particles are vibrating in the same phase
• B. amplitude of all the particles is equal
• C. particles of the medium execute S.H.M.
• D. wave velocity depends upon the nature of the medium

Answer 1

Answer: (B), (C), (D)

The correct options are
B wave velocity depends upon the nature of the medium
C amplitude of all the particles is equal
D particles of the medium execute S.H.M.

During propagation of a plane progressive mechanical wave amplitude of all the particles is equal, particle of the medium execute S.H.M, wave velocity depends upon the nature of the medium and all the particles are vibrating in the different phase.

Hence $B,C$ and $D$ are correct options.
