Sound Wave Review

Front

What do mechanical waves, like sound waves, require to transfer energy?

Back

Medium

Front

Which graph shows a higher frequency, B or C?

Back

Graph C shows a higher frequency.

Front

What does a higher amplitude in a sound wave indicate?

Back

A higher amplitude indicates a louder sound.

Front

If two graphs have the same frequency, what can be said about their pitch?

Back

They have the same pitch.

Front

Which graph represents a sound wave that will transfer more kinetic energy?

Back

Graph 1 transfers more kinetic energy.

Front

What is the definition of frequency in the context of sound waves?

Back

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

Front

What is amplitude in sound waves?

Back

Amplitude is the height of the wave, which determines the loudness of the sound.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency corresponds to a higher pitch.

Front

What happens to sound waves in a vacuum?

Back

Sound waves cannot travel in a vacuum because they require a medium.

Front

What is the speed of sound in air at room temperature?

Back

Approximately 343 meters per second.
