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.

Front

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.

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.

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 happens to the amplitude of a sound wave when the sound is made louder?

Back

The amplitude of the sound wave increases.

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.
