Question 9
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.
Watch how the vibrating tuning fork causes ripples in the water (Figure 11.10). What do the ripples represent?
Discuss in groups and share your findings with the class. You may use the Internet or other sources of information to help you.
