Observing a Wave Practice

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is the amplitude of a wave?

Back

The amplitude is the maximum distance from the zero line to the crest or trough of the wave.

Front

What is a crest in a wave?

Back

The crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

The trough is the lowest point of a wave.

Front

What does wavelength refer to in a wave?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is the zero line in wave terminology?

Back

The zero line is the baseline or equilibrium position of the wave, where the wave has no energy.

Front

How is energy related to waves?

Back

Waves carry energy through vibrations, and the amount of energy is related to the amplitude of the wave.

Front

What happens to the amplitude of a wave if it has more energy?

Back

If a wave has more energy, its amplitude increases.

Front

Can a wave exist without energy?

Back

No, a wave cannot exist without energy; a wave with no energy is represented by the zero line.

Front

What is the relationship between wavelength and frequency?

Back

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