Front

Define a mechanical wave.

Back

A mechanical wave is a disturbance that travels through a medium (solid, liquid, or gas) and requires a medium to propagate.

Front

What is the difference between a crest and a trough in a wave?

Back

A crest is the highest point of a wave, while a trough is the lowest point.

Front

What is amplitude in the context of waves?

Back

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

Front

What is wavelength?

Back

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

Front

What is frequency in relation to waves?

Back

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