Question

A transverse wave is transporting energy from east to west. The particles of the medium will move

• A. east to west only
• B. both eastward and westward
• C. north to south only
• D. both northward and southward

Answer 1

The correct option is D

both northward and southward

1. The given diagram shows wave propagation and displacement of particles which is perpendicular to the direction of propagation.
2. We know that waves transport energy from one place to another. The direction of transportation of energy is the same as the direction of propagation of the wave.
3. Also in a transverse wave, the particles in the medium oscillate in a direction perpendicular to the direction of propagation.
4. Therefore, the particle will oscillate in a direction perpendicular to the propagation of energy.
5. As mentioned in the question, the transverse wave is transporting energy from east to west. Thus, the particle in the medium will move both northward and southward.

Hence, option (d) is correct.
