TWO AQUARIUMS ARE COMPLETELY FULL OF WATER, but the pressure at the bottom of aquarium A is greater than at the bottom of aquarium B. The cause of this could be

A is shaped like a box and B is shaped like a cylinder.

The water in A is deeper than it is in B

A contains freshwater and B contains seawater

Which of the following CAN CHANGE THE FREQUENCY OF A WAVE?
