Wave and Sound Review

Sound is able to travel faster in solids than in air because the molecules in a solid are

• closer together than air molecules
• more easily moved than air molecules
• moving faster than air moleculesmoving faster than air molecules
• larger than air molecules

Bruce plays his violin every Friday night for the symphony. Before he plays, he plucks each string to see if his violin is in tune. Which is most responsible for the generation of sound waves from his violin?

• material of the violin
• vibrations of the string
• movement of the violin
• composition of the string
