What is wavelength?

Back

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

What is amplitude?

Back

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

What is the relationship between frequency and wavelength?

Back

Higher frequency waves have shorter wavelengths, and lower frequency waves have longer wavelengths.

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 the distance a wave travels in a given amount of time, calculated as speed = frequency × wavelength.
