Activity 10.3 Let us investigate

Aim: To show that sound can travel through solids.

Procedure: Let you and your friend stand on opposite sides of a desk in the classroom.

Observation: When the desk is tapped and the ear is in air, a faint sound is heared and when the ear is placed against the desk, the sound becomes louder and clearer as vibrations travel through the desk to the ear.

Conclusion: This shows that sound can travel through solids. It travels better in solids because particles are closely packed, allowing vibrations to pass easily.
