What technology uses sound waves?

What technology uses sound waves?

Sonar
Sonar (sound navigation and ranging) is a technology that uses acoustical waves to sense the location of objects in the ocean. The simplest sonar devices send out a sound pulse from a transducer, and then precisely measure the time it takes for the sound pulses to be reflected back to the transducer.

What term describes the use of reflected sound waves to determine distances or locate objects?

The word sonar comes from the initial letters of sound navigation and ranging. Navigation, means finding your way on the ocean or in the air and ranging means finding the distance between objects. The sonar device detects the reflected waves.

How is sound reflected and refracted absorbed?

When a sound wave meets a boundary it may be: Whether a sound wave is reflected, refracted, or absorbed depends on the densities of the materials either side of the boundary. If the densities are very different then reflection is more likely.

Is a reflected sound wave?

Sound is actually a type of mechanical wave. Just like other waves can be reflected, such as light waves, sound waves can also experience reflection.

What is the practical applications of the reflection of sound waves?

(a) Reflection of sound is used to measure the distance and speed of underwater objects. This method is known as SONAR. (b) Working of a stethoscope is also based on reflection of sound. In a stethoscope, the sound of the patient’s heartbeat reaches the doctor’s ear by multiple reflections of sound.

What system uses reflected sound waves to locate objects underwater?

Sonar stands for sound navigation and ranging. It is used to locate underwater objects such as submarines. Ultrasonography is the use of reflected ultrasound waves to “see” inside the body.

Which is the use of sound to identify the distances and positions of objects?

sonar: An object-finding system that uses sound waves to determine the distance, speed of and direction to objects within its range.

Is sound reflected or refracted?

Refraction of sound waves is most evident in situations in which the sound wave passes through a medium with gradually varying properties. For example, sound waves are known to refract when traveling over water.
