Sound Waves

Front

What is a sound wave?

Back

A sound wave is a type of energy wave that travels through a medium, usually air, but it can also move through solids and liquids.

Front

How is sound made?

Back

Sound is created by vibrations, causing nearby air particles to vibrate and transfer energy to adjacent particles.

Front

What are compressions in sound waves?

Back

Compressions are regions in a sound wave where particles of the medium are densely packed together, leading to an increase in pressure.

Front

What is wavelength?

Back

Wavelength is the distance between two successive identical points in the wave pattern.

Front

What is frequency?

Back

Frequency refers to how often the particles in the medium vibrate as the wave passes through, perceived as the pitch of the sound.

Front

What is Hertz (Hz)?

Back

Frequency is measured in Hertz (Hz), representing cycles per second.

Front

What are infrasonic and ultrasonic sounds?

Back

Infrasonic sounds have frequencies below 20 hertz, while ultrasonic sounds have frequencies above 20,000 hertz.

Front

What is echolocation?

Back

Echolocation is a process where sound waves are emitted and their echoes are used to determine the location and characteristics of objects.
