a) mechanical transverse waves can propagate through all mediums

b) longitudinal waves can propagate through solids only

c) mechanical transverse waves can propagate through solids only

d) longitudinal waves can propagate through a vacuum

Answer:

The correct option is c) mechanical transverse waves can propagate through solids only

Explanation:

1. Mechanical transverse waves can’t go all the way through a medium. Because there is no mechanism for driving motion perpendicular to the propagation of the wave, they can only propagate through solids and not in gas or liquid.
2. The longitudinal wave can travel through any medium.
3. Only solids may propagate mechanical transverse waves.
4. There is no way for a longitudinal wave to propagate in a vacuum.
As a result, option C is right.
