Make waves with a dripping faucet, audio speaker, or laser! Adjust frequency and amplitude, and observe the effects. Hear the sound produced by the speaker, and discover what determines the color of light. • Make waves with water, sound, and light and see how they are related. • Discuss wave properties using common vocabulary. • Explain how changing the frequency and amplitude affects the characteristics of the wave. • Design an experiment to measure the speed of the wave.
