Question

1. what purpose do waves serve?

a. to make sounds
b. to transfer energy
c. to melt things
d. to break down materials

Explanation:

Waves are fundamental phenomena that carry energy from one location to another without transporting matter. While some waves (like sound waves) create sounds, some high-energy waves can break down or melt materials, these are specific effects, not the core purpose of all waves. The universal, defining function of waves is energy transfer.

Answer:

B. To transfer energy
