Questions: Pitch and Volume

Question 1

What determines the pitch of a sound?

• A. How big the vibrations are
• B. How fast the vibrations are
• C. How far the sound travels
• D. How long the sound lasts

Answer: (B)

Pitch depends on the frequency (speed) of vibrations. Faster vibrations produce a higher pitch, and slower vibrations produce a lower pitch.

Question 2

A louder sound is made by bigger vibrations.

• T. True
• F. False

Answer: True

The size (amplitude) of the vibration determines the volume. Bigger vibrations push more air and create louder sounds.

Question 3

How could you make a guitar string produce a higher pitch sound?

Model answer: Tighten the string (or press it down to shorten the vibrating length).

A tighter or shorter string vibrates faster, which produces a higher pitch. This is how guitarists play different notes.
