Answer 2

Question:

How can you explain the sound has energy?

Answer:

Sound has energy:

Take a plastic bottle and a cell phone. Cut the top of the bottle so that it looks like a glass. Play ongs on the mobile phone in high volume and place it in the bottle. Close the mouth of bottle with a balloon using rubber band so that it covers the bottle as shown in the figure and stretch it tightly so as to behave like a diaphragm. Place some sugar crystals or small sand particles on the balloon diaphragm and observe the movement of particles. Do the same activity after removing the phone from the bottle.So we can prove that sound has energy.
