Sound Waves Quiz

Which property of a sound wave determines how high or low a sound is perceived (its pitch)?

• Amplitude

• Frequency

• Wavelength

• Speed

What does the amplitude of a sound wave represent?

• The speed of the sound

• The loudness or intensity of the sound

• The pitch of the sound

• The direction of the sound

Which of the following best shows one wavelength of a sound wave?

• 
• 
• 
• 

If the frequency of a sound wave increases, what happens to its pitch?

• The pitch becomes lower

• The pitch becomes higher

• The pitch stays the same

• The pitch disappears

Which sound wave has the highest frequency?

• 
• 
• 
• 

Given two sound waves with the same amplitude but different frequencies, which property will be different between the two sounds?

• Volume

• Pitch

• Speed

• Direction

A student increases the amplitude of a sound wave while keeping the frequency the same. What effect will this have on the sound?

• The sound will become higher in pitch

• The sound will become louder

• The sound will become softer

• The sound will become lower in pitch

A sound wave is represented in a diagram with very close-together wave peaks. What does this indicate about the sound?

• It has a low frequency and low pitch

• It has a high frequency and high pitch

• It has a low amplitude and is quiet

• It has a high amplitude and is loud
