Front

Why do we use carpets in places like libraries?

Back

Carpets help absorb sound, reducing noise and creating a quieter environment.

Front

What happens to the frequency of a sound wave when its pitch is lowered?

Can sound travel through air?

Back

Yes, sound can travel through air, which is a gas.

Front

What is an example of sound energy in everyday life?

Back

Examples include music from instruments, voices speaking, and sounds from machines.
