Waves Review #1

Front

What is the definition of wavelength?

Back

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

Front

What is a crest in a wave?

Back

The highest point of a wave, often referred to as the peak.

Front

What is a trough in a wave?

Back

The lowest point of a wave, opposite of the crest.

Front

What type of wave is characterized by particle movement parallel to the direction of wave propagation?

Back

Longitudinal wave.

Front

What is a medium in the context of waves?

Back

A substance (solid, liquid, or gas) through which a wave can travel.

Front

Why can't sound be heard in outer space?

Back

Because there is no medium for the sound waves to travel through.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves have particle movement perpendicular to wave direction, while longitudinal waves have particle movement parallel to wave direction.

Front

What is amplitude in a wave?

Back

The maximum displacement of points on a wave from the rest position, indicating the wave's energy.

Front

How do you measure the wavelength of a longitudinal wave?

Back

By measuring the distance from one compression to the next compression.

Front

What is frequency in relation to waves?

Back

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