Question 8
In groups, demonstrate sound vibrations. Work on a solid surface like a wooden block or a tabletop. Ask your teacher for a rubber pad, a tuning fork and a bowl with water.
Strike the tuning fork against the rubber pad. Place the fork's prongs just above the surface of the water (Figure 11.9). What do you observe? Why does this occur?
Discuss in groups and share your findings with the class. You may use the Internet or other sources of information to help you.
