What is a wave?

Back

A wave is a disturbance that travels through space and matter, transferring energy from one place to another.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves (which require a medium, like sound waves) and electromagnetic waves (which do not require a medium, like light waves).

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through.

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a wave that can travel through a vacuum and does not require a medium, such as light.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second, measured in hertz (Hz).

Front

What is amplitude?

Back

Amplitude is the height of a wave from its rest position to its crest or trough, indicating the energy of the wave.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is the speed of a wave?

Back

The speed of a wave is how fast the wave travels through a medium, calculated by multiplying frequency and wavelength.
