direction as it passes through an opening.
B. A diffracted sound wave bounces back to the place of origin. A reflected sound wave is
absorbed as it passes through an opening.
C. A reflected sound wave bounces back to the place of origin. A diffracted sound wave
changes direction as it passes through an opening.
