A guitarist plucks a string gently first, and then plucks the exact same string with much greater force. How does the second sound compare to the first?
It has a higher pitch
It has greater loudness
It travels faster to the listener
It has a lower frequency
Solution
Plucking a string with greater force increases the amplitude of vibration, which increases the loudness without changing the pitch.
