Final answer:
A surface wave is an example of a mechanical wave because it requires a medium to transfer its energy.
Step-by-step explanation:
Mechanical waves require a medium to transfer their energy. A surface wave is an example of a mechanical wave because it propagates through a medium, such as water or the ground. Radio waves, microwaves, and light waves, on the other hand, are not mechanical waves because they can propagate through a vacuum, which means they do not require a medium to transfer their energy.
