What is a longitudinal wave?

Back

A wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What is compression in a wave?

Back

Compression is the region in a longitudinal wave where the particles are bunched together.

Front

What is rarefaction in a wave?

Back

Rarefaction is the region in a longitudinal wave where the particles are spread apart.

Front

What is a medium in the context of waves?

Back

A medium is the substance through which a wave travels, such as solid, liquid, or gas.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not.

Front

What are the two main types of mechanical waves?

Back

The two main types of mechanical waves are longitudinal waves and transverse waves.

Front

What are crests and troughs?

Back

Crests are the highest points of a transverse wave, while troughs are the lowest points.

What is wavelength?

Back

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