Cram for Sound

Mechanical waves...

• can travel through space
• need a medium (solid, liquid, or gas) to travel
• make light
• do NOT need a medium to travel

A change in frequency causes...

• a change in speed
• a change in loudness
• a change in pitch
• a change in spacing of the waves

A change in amplitude causes...

• a change in speed
• a change in loudness
• a change in pitch
• a change in spacing of the waves
