8.2 Sound Lessons 1-6 Review

Front

What is sound?

Back

Sound is a type of energy made by vibrations that travel through the air (or another medium) and can be heard when they reach a person's or animal's ear.

Front

What is amplitude in sound waves?

Back

Amplitude refers to the height of the sound wave, which determines the loudness of the sound. Higher amplitude means louder sound.

Front

Define frequency in the context of sound.

Back

Frequency is the number of vibrations or cycles that occur in a sound wave per second, measured in Hertz (Hz).

Front

What is pitch?

Back

Pitch is the perceived frequency of a sound; it determines how high or low a sound is.

Front

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 does it mean if two sounds have the same amplitude?

Back

If two sounds have the same amplitude, they are perceived to be at the same loudness level.

Front

What is the speed of sound?

Back

The speed of sound is the distance that sound waves travel in a given amount of time, typically around 343 meters per second in air at room temperature.

Front

What is a sound wave?

Back

A sound wave is a longitudinal wave that is created by vibrating objects and travels through a medium (like air, water, or solids).

Front

What is compression in sound waves?

Back

Compression is the part of a sound wave where the particles of the medium are close together, resulting in increased pressure.

Front

What is rarefaction in sound waves?

Back

Rarefaction is the part of a sound wave where the particles of the medium are spread apart, resulting in decreased pressure.
