Front

What are the two main types of waves?

Back

Mechanical waves and electromagnetic 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.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

Front

What is wavelength?

Back

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

Front

What is the formula for wave speed?

Back

Front

What is frequency in the context of waves?

Back

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