OpenSciEd Sound Review

Front

What is the valley in a sound wave?

Back

The valley is the lowest point of a wave, representing the minimum displacement of the medium from its rest position.

Front

What is the peak in a sound wave?

Back

The peak is the highest point of a wave, representing the maximum displacement of the medium from its rest position.

What is energy in the context of sound waves?

Back

Energy is what moves across the sound wave, allowing sound to travel through a medium.

What does frequency refer to in sound waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz). Higher frequency means a higher pitch.

Front

What is amplitude in a sound wave?

Back

Amplitude is the height of the wave from its rest position, which determines the loudness of the sound.

What is wavelength in a sound wave?

Back

Wavelength is the distance between two consecutive peaks or valleys in a wave.

Front

How do air particles move when a speaker vibrates?

Back

Air particles move because the speaker pushes on them, creating compressions and rarefactions in the air.

What is the relationship between frequency and pitch?

Back

Higher frequency corresponds to a higher pitch, while lower frequency corresponds to a lower pitch.

Front

What happens to sound energy as it travels through different mediums?

Back

Sound energy can be absorbed, reflected, or transmitted depending on the properties of the medium.

What is the difference between a compression and a rarefaction in a sound wave?

Back

A compression is a region where particles are close together, while a rarefaction is a region where particles are spread apart.
