Solution 1
Sound is propagated in the form of waves in solids. It can be explained clearly from the below examples:
- Place your ear on one end of a long table. Ask your friend to tap the table from the other end. You can hear the produced sound. Sound reaches your ear after travelling through the table. This indicates that sound can travel through solids and in the form of waves.
- A stethoscope is another example of sound travelling through solids. Doctors use stethoscopes to listen to our heartbeat.
Solution 2
Sound propagates with maximum speed through the solid medium. We can hear the sound of a train that is far off by placing our ear to the railway track. If we knock at the door. The person inside the room can hear it clearly.
