Waves Review #1

Front

What is a medium in the context of waves?

Back

A medium is a substance (solid, liquid, or gas) that the energy of a wave can travel through.

Front

What is a trough in a wave?

Back

The trough is the area around the lowest point of a wave.

Front

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

Back

Longitudinal wave.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particle movement is perpendicular to the direction of wave propagation.

Front

What is the amplitude of a wave?

Back

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

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a given point in a certain amount of time, usually measured in Hertz (Hz).

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is a compressional wave?

Back

A compressional wave, also known as a longitudinal wave, is a wave in which the particles of the medium move back and forth in the same direction as the wave.

Front

What happens to sound waves in outer space?

Back

Sound waves cannot travel in outer space because there is no medium for them to travel through.

Front

What is the crest of a wave?

Back

The crest is the area around the highest point of a wave.
