Answer:
A wave is like water rippling in a pond.
Step-by-step explanation:
Water tanks are used to examine water waves and their properties. Two types of waves, circular and linear, can be produced in water. The crests of the waves behave like convergence on the target and it is observed in the lower part of the tank as a clear zone. On the other hand, the depressions darken in the lower part of the water tank.
