sound wave

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. 

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

A wave with a large wavelength will have a ______ frequency and _____ energy

• high, low

When a sound is louder what measurement gets bigger?

• Frequency 
• Amplitude 
• Wavelength 
• Crest

A wave that requires a medium through which to travel

• mechanical wave
• chemical wave
• electromagnetic wave
• pitch

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.
