Sound Waves Quiz

If the distance represented by the letter A were increased, how would it change the way the sound was heard?

• The sound would be higher. 
• The sound would be lower. 
• The sound would be softer. 
• The sound would be louder. 

As the fire truck approached Mary, the pitch of the siren got higher. Once the fire truck passed and moved away, the siren's pitch got lower. This change in pitch is because of a change in the sound wave's

• concussion. 
• amplitude. 
• reflection.
• frequency. 

When comparing the two waves that are shown, how would Wave A (green wave) differ than Wave B (black wave)?

• Wave A and B have the same amplitude, but wave B (black) has a lower pitch.
• Wave A and B have the same amplitude, but Wave A has a lower pitch. 
• Wave A and B have the same pitch, but Wave A is a softer sound. 
• Wave A and B have the same pitch, but Wave B is a softer sound. 

What does pitch depend on?

• amplitude 
• frequency
• intensity 
• volume of sound

When a sound is louder what measurement gets bigger?

• Frequency 
• Amplitude 
• Wavelength 
• Crest

The number of wavelengths that pass a point each second

• crest
• amplitude
• frequency
• pitch

The shorter the wavelength the 

• shorter the frequency
• higher the freuqnecy
• frequency stays the same
• less energy

Sound is produced by

• music
• vibrations of molecules
• Electromagnetic Waves 
• Transverse Waves 

If distance C on the diagram increased, what would happen to the pitch? 

• The pitch would be louder. 
• The pitch would be softer. 
• The pitch would be higher. 
• The pitch would be lower. 

Which feature of sound is determined by amplitude?

• Pitch
• Smoothness
• Loudness
• A Wave
