उत्तर
Mount two identical tuning forks A and B of same frequency upon two separate sound boxes such that their open ends face each other as shown.

If the prong A is struck on a rubber pad, it starts vibrating. On putting A on its sound box, tuning
fork B also starts vibrating and a loud sound is heard. The vibrations produced in B are due to
resonance.
