What are some applications of sound waves?

Ultrasound waves are used to detect objects. A ringing telephone, a honking horn, and the sound of a friend’s voice are all reminders of how important sound is. But sound has uses that go beyond communication. For example, some animals and people use reflected ultrasound waves to detect objects.

What is an example of sound wave refraction?

For example, sound waves are known to refract when traveling over water. Since water has a moderating effect upon the temperature of air, the air directly above the water tends to be cooler than the air far above the water. Sound waves travel slower in cooler air than they do in warmer air.

What are two applications of refraction?

Applications of Refraction of Light

• A lens uses refraction to form an image of an object for various purposes, such as magnification.
• Spectacles worn by people with defective vision use the principle of refraction.
• Refraction is used in peepholes of house doors, cameras, movie projectors and telescopes.

What is refraction of sound wave?

When sound waves move from one medium to another, there will be changes to the velocity (or speed), frequency and wavelength of the sound wave. This change in velocity can also result in a change of direction of the sound wave – also known as refraction.

How is the refraction of a sound wave used?

The refraction of a sound wave can change speed and direction, for example – light traveling from air into water. Following are the practical applications of reflection of sound waves are: Reflection of sound is used to measure the distance and speed of underwater objects. This method is known as SONAR.

Which is an example of the reflection of sound?

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

Which is an example of the application of refraction?

The Applications of Refraction. Refraction is a phenomenon that occurs when waves passing from one transparent medium to another bend at the boundary between the two mediums due to a change in the speed of the waves. A naturally occurring example of refraction is the rainbow, which is created when sunlight is refracted by raindrops.

When does reflection, refraction, and diffraction occur?

Reflection, Refraction, and Diffraction. Like any wave, a sound wave doesn’t just stop when it reaches the end of the medium or when it encounters an obstacle in its path. Rather, a sound wave will undergo certain behaviors when it encounters the end of the medium or an obstacle.
