What are the two main types of waves?

Back

Transverse waves and longitudinal waves.

Front

Define a transverse wave.

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave's travel.

Define a longitudinal wave.

Back

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

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that the particles of a medium move from their rest position when a wave passes through.

How does sound travel through different mediums?

Back

Sound travels faster in solids than in liquids, and faster in liquids than in gases because molecules are closer together in solids.

What is a compressional wave?

Back

A compressional wave is a type of longitudinal wave where the particles of the medium are compressed and then rarefied.
