Question

Which points represent the rarefactions in the graphical wave representation shown?

  1. AEIM
  2. BFJ
  3. DHL
  4. CGK

hintHint:

The points CGK in the given graphical representation represents the points of rarefaction.

The correct answer is: CGK


    • The sound waves produce upper and lower pressure points on oscillation.
    • Rarefaction is the peak produced downwards that has less pressure.
    • The points CGK represents the points of rarefaction.
