Sound

The frequency of a sound wave determines...

• pitch (high/low)

• volume dynamics (loud/soft)

• Timbre

• How much hearing loss one suffers

The amplitude of a sound waves determine...

• pitch high/low

• volume/ dynamics (loud/soft)

• Timbre (what sound is like)

• How much hearing loss one suffers

Which violin string would have the highest pitch?

• long, thick string

• short, thick string

• short, thin string

• long, thin string

If two violin strings are vibrating at the same time and produce the same pitch they must be:

• the same length

• made of the same material

• tightened the same tension

What is true about Wave A and Wave B?

• Wave A has a higher amplitude which means Wave A will have a louder sound than Wave B.

• Wave A has a lower amplitude which means Wave A will have a softer sound than Wave B.

• Wave A and Wave B have the same amplitude.

• None of the above
