Explanation:
Most waves appear complex because they result from two or more simple waves that combine as they come together at the same place at the same time—a phenomenon called superposition. Waves superimpose by adding their disturbances; each disturbance corresponds to a force, and all the forces add

Answer:
The water is 1310.75 meters deep.
Explanation:
The question gives us the speed of sound and the time the sonar signal takes to travel to the bottom of the water and back.
To find out the distance, we should first divide the time in half, so we only consider the time taken for the sound to reach the bottom of the water body.
This means:
Time = 1.75 / 2 = 0.875 seconds
The distance traveled in this time is:
Distance = Speed * Time
Distance = 1498 * 0.875
Distance = 1310.75 meters
Thus, the water is 1310.75 meters deep.
