Answer:
When we throw a pebble in the center of a pond: (c) only the disturbance travels from the center towards the shore.
Explanation:
- When we throw a pebble in the center of a pond then around point of impact caused disturbance consists of combination of transverse and longitudinal waves .
- When a pebble is thrown in still water of a pond, a circular pattern of alternate crests spread out. The kinetic energy makes the particles to oscillate that comes in contact with that crests. The energy gets transferred to the next layer which also begins to oscillate now. Thus it creates the disturbance or waves that move forward and not the particles of the medium.
- A wave can be referred as a disturbance that propagates from the place it was created. The simplest waves repeat themselves for several cycles with simple harmonic motion.
