A rubber band is stretched between two pins on a board and plucked. If the rubber band is stretched tighter and plucked again, what happens to its sound?
  1. Vibrations slow down, producing a deeper pitch
  2. Vibrations speed up, producing a higher pitch
  3. Vibrations stop because tension prevents movement
  4. The sound travels much slower through the surrounding air

Solution

Increasing the tension in a stretched string or band increases its frequency of vibration, yielding a sound of higher pitch.
