part 5 : Wavelength 9 . The wavelength is the distance between the top of one wave and the top of the other. Measure the wavelength of one of your waves. Draw a diagram below showing what you measured and its length. Include units in your diagram. 10. Create transverse waves using different frequencies. What relationship do you notice between wavelength and frequency? Part 6 : Wave Reflection 11. Send a single transverse wave to your partner and watch the reflected wave return. Describe how the reflected wave looks compared to the original wave. 12. Draw a diagram showing the differences between the original wave and the reflected one. Part 7 : Wave Interference 13. When waves combine, they can add together or cancel each other out; we call this concept interference. Let's see if we can make both of these cases happen. 14. Create two transverse waves at the same time. To do this, you and your partner will have to vibrate the spring toy simultaneously the same amount so the wave pulses start on the same side of the spring toy. What do you notice happens to the amplitude when the wave pulses hit? 15. Let's repeat this. However, this time create two waves traveling on different sides of the spring toy. What do you notice happens to the amplitude when the wave pulses hit? Part 8 : Summing it Up Let's combine what you have learned in this investigation. You may need to consult your textbook to answer some of the questions. 16. Draw a transverse wave below. Label the crest, trough, amplitude, and wavelength. 17. Draw a longitudinal wave below. Label the wavelength
