\nMaterial Required: A table \nProcedure: Lean over a table so that one of our ears touches the table. Close the other ear with the help of the hand. Now, ask your friend/a person to gently tap on the table at a point a metre away from your ear. When your friend taps on the table, the sound waves travel through the table to your ear. This is why you can hear the sound even though your ear is touching the table.

Conclusion: This experiment proves that sound can travel through solids.
\n\n
Sound waves travel through solids by causing the atoms of the solid to vibrate. The faster the atoms vibrate, the higher the frequency of the sound wave. The higher the frequency of the sound wave, the higher the pitch of the sound.
