Final answer:
The statement is true; a pebble dropped in water creates ripples that constitute a pulse wave, characterized by a single disturbance moving through a medium.
Step-by-step explanation:
Is a pebble dropped in water an example of a pulse wave?
The statement that a pebble dropped in water is an example of a pulse wave is true. When a pebble is dropped into a body of water, it creates a disturbance that travels away from the point of impact in a series of ripples or waves. This phenomenon is indeed an example of a pulse wave. A pulse wave is typically characterized by a single disturbance that moves through a medium, and in the case of the pebble in the water, the creation of the ripples fits this definition. Pulse waves are important in various fields, including physics, engineering, and even medical diagnostics where they might be used to measure heart rate.
