G8 Waves Unit Review

Front

What is pitch in sound?

Back

Pitch refers to how high or low a sound seems, determined by the frequency of the sound wave.

Front

What is amplitude in a wave?

Back

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

Front

Define frequency in the context of waves.

Back

Frequency is the number of times a wave repeats in a given amount of time, usually measured in Hertz (Hz).

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the particles of the medium move parallel to the direction of the wave's travel.

Front

What is compression in a longitudinal wave?

Back

Compression is the part of a longitudinal wave where the particles of the medium are close together.

Front

What is rarefaction in a longitudinal wave?

Back

Rarefaction is the part of a longitudinal wave where the particles of the medium are spread apart.

Front

What is the relationship between amplitude and brightness of light?

Back

The brighter the light, the higher the amplitude of the wave.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

How does frequency affect pitch?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What is the formula for calculating wave speed?

Back

Wave speed = frequency × wavelength.
