Mechanical Waves

Front

What do mechanical waves require to travel?

Back

Mechanical waves must travel through a medium.

Front

What is the term for the distance between the rest position and the crest or trough of a wave?

Back

Amplitude.

Front

What determines the pitch of sound waves?

Back

Frequency.

Front

Can sound waves travel through a vacuum or outer space?

Back

False.

Front

What is the term for the distance between any two adjacent crests on a wave?

Back

Wavelength.

Front

What is a mechanical wave?

Back

A mechanical wave is a disturbance that travels through a medium, transferring energy from one location to another.

Front

What are the two main types of mechanical waves?

Back

Transverse waves and longitudinal waves.

Front

In a transverse wave, how do the particles of the medium move?

Back

The particles move perpendicular to the direction of the wave's travel.

Front

In a longitudinal wave, how do the particles of the medium move?

Back

The particles move parallel to the direction of the wave's travel.

Front

What is the relationship between frequency and wavelength in a wave?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.
