Interference of sound waves produce beats When the compressions from two tuning forks arrive at the same time, constructive interference occurs, and the sound is louder. When a compression and rarefraction arrive at the same time, destructive interference occurs, and the sound is softer. The series of loud and soft sounds are called beats

sounder produces sound waves that travel from a ship to the seafloor. The waves echo, or bounce, off the seafloor and back to the ship. The echo sounder records the time it takes the echo to return. When the ocean is deeper, the time it takes for the sound waves to bounce back is longer. Scientists calculated ocean depths and used these data to ...
