Sound Wave

Sound is a form of

• energy

• power

• work done

• force

Sound produced from

Speed of waves is different is every medium. The fastest is via

This experiment is to determine

• object that can reflect sound wave

• object that can absorbed sound wave

• speed of propagation of sound wave in air

• speed of propagation of sound wave in solid

Characteristics of a good reflector are

• hard

• soft

• smooth

• rough

If distance C on the diagram decreased, what would happen to the pitch? 

• The volume would be louder. 
• The volume would be softer. 
• The pitch would be higher. 
• The pitch would be lower.
