Sound Unit Final Assessment part 1

Front

What is amplitude in sound waves?

Back

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

Front

What does frequency mean in the context of sound?

Back

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

Front

What is the relationship between frequency and pitch?

Back

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

Front

What type of wave is produced by a high pitch sound?

Back

A high pitch sound produces a high frequency wave.

Front

What type of wave is produced by a low pitch sound?

Back

A low pitch sound produces a low frequency wave.

Front

How does amplitude affect sound?

Back

Amplitude affects the loudness of the sound; higher amplitude means louder sound, while lower amplitude means softer sound.

Front

What happens to the vibrations when a sound is high pitched?

Back

The vibrations move quicker and more frequently.

Front

What happens to the vibrations when a sound is low pitched?

Back

The vibrations move slower and less frequently.

Front

What is the effect of a hard push on a stick in terms of wave amplitude?

Back

A hard push creates a wave with high amplitude.

Front

What is the effect of a soft push on a stick in terms of wave amplitude?

Back

A soft push creates a wave with low amplitude.
