How do sound waves travel between a boat and a submarine in sonar technology?
A. Because of water particles.
B. Because of water waves.
C. Because of water ripples.
D. Because of water currents.
B?
No, what if the water is calm?
Yes, the correct answer is B. Sound waves travel between a boat and a submarine in sonar technology because of water waves.
Explanation:
Sonar stands for "sound navigation and ranging," and it is a technology that uses sound waves to detect and locate objects underwater. In sonar systems, sound waves are emitted by a transmitting device, such as a sonar projector or transducer, attached to a boat or submarine. These sound waves travel through the water medium and bounce off objects in their path, including the target object, such as another boat or submarine.
The sound waves, which are essentially vibrations, propagate through the water in a wave-like motion similar to the way water waves travel. When the sound waves encounter an object, they reflect off it and return to the transmitting device. By measuring the time it takes for the sound waves to travel to the object and back, along with other factors like the frequency and intensity of the wave, the sonar system can determine the distance, location, and characteristics of the object.
Therefore, it is the motion of water waves that allows sound waves to travel between a boat and a submarine in sonar technology. It is important to note that although there may be water particles, ripples, or currents present in the water, it is the water waves themselves that primarily allow for the propagation of sound waves in sonar systems.
