What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

What are mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through.

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium, such as light waves.

What is frequency?

Back

Frequency is the number of waves that pass a given point in a certain amount of time, usually measured in Hertz (Hz).

What is wavelength?

Back

Wavelength is the distance between two consecutive points of the same phase in a wave, such as crest to crest or trough to trough.

What is wave speed?

Back

Wave speed is the speed at which a wave travels through a medium, calculated as the product of frequency and wavelength.

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, and vice versa.

What is a sound wave?

Back

A sound wave is a mechanical wave that travels through a medium (like air) and is produced by vibrating objects.

How does a sound wave interact with a human ear?

Back

A sound wave vibrates the eardrum, allowing us to perceive sound.
