Waves Flashcard 8th grade

Front

What is a wavelength?

Back

The distance between two consecutive points of a wave that are in phase, such as from crest to crest or trough to trough.

Front

What does amplitude measure in a wave?

Back

Amplitude measures the maximum distance the wave vibrates from its rest position, indicating the energy carried by the wave.

Front

What is a compression in a wave?

Back

A region in a longitudinal wave where the particles are closest together.

Front

What is a rarefaction in a wave?

Back

A region in a longitudinal wave where the particles are spread apart.

Front

What is the crest of a wave?

Back

The highest point of a wave.

Front

What is the trough of a wave?

Back

The lowest point of a wave.

Front

How does frequency relate to waves?

Back

Frequency is the number of waves that pass a point in one second, 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 the formula for wave speed?

Back

Wave speed = Wavelength × Frequency.

Front

What is a standing wave?

Back

A wave that remains in a constant position, formed by the interference of two waves traveling in opposite directions.
