Sound is produced when matter

• is cold
• vibrates
• Option 3
• changes frequency
• is able to be heard

The speed of sound is determines by

• Temperature
• Stiffness
• Density
• All of the above

The pitch of a sound depends on the

• vibration
• frequency
• density
• loudness

The faster the medium vibrates the ---------------------the pitch.

• higher
• lower

The slower the medium vibrates

• higher
• lower

Which phase of matter will sound travel fastest in?

• warm weather because of lower frequency
• solids because the molecules are closer together

The intensity of a sound is the amount of energy carried by the wave and determines how

• loud
• amplitude
• stiff
• high

Amplitude is

• frequency
• decibel
• amount of energy transfered in the wave
• the density of the wave
