Unit 06: Sound Practice

Front

What is pitch in sound?

Back

Pitch is the property of sound that determines how high or low a sound is. It is affected by the frequency of the sound wave.

Front

What medium transmits sound the fastest?

Back

Steel transmits sound the fastest compared to air, water, and vacuum.

Front

How does sound travel through air?

Back

Sound travels through air by vibrating air molecules.

Front

What is a compression wave?

Back

A compression wave is a type of wave where particles move back and forth in the same direction as the wave.

Front

What happens to particles in rarefactions?

Back

In rarefactions, particles are spread out.

Front

What is loudness in sound?

Back

Loudness is the perception of the strength or intensity of a sound, often related to the amplitude of the sound wave.

Front

What is an echo?

Back

An echo is a reflection of sound that arrives at the listener after a delay.

Front

What is the speed of sound in air?

Back

The speed of sound in air is approximately 343 meters per second at room temperature.

Front

What is the relationship between frequency and pitch?

Back

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

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.
