Period: Date: Homework # 7 - Standing Waves Handout Problems: Questions 1 - 4 are based on the diagram below showing a standing wave on a 3 meter string. 1. How many nodes are in the standing wave? How many antinodes are in the wave? 2. What is the wavelength of the standing wave? 3. Show by means of a diagram how a standing wave with a 6 meter wavelength would fit in the 3 meter string shown above. Repeat with a wave of 1.5 meter wavelength. 4. Explain why a wave with a 2.5 m wavelength would NOT be able to produce a standing wave in the same 3 meter long string. 5. Maximum destructive interference between two waves occurs when the waves are out of phase by degrees
