If your diagram represented 6 meters in length and 1 second of time what would be the wavelength, frequency and period of the wave. 5. Wave Speed a. Write the equation to calculate wave speed from wavelength and frequency. b. How would the wavelength change if the speed of the wave decreases while frequency remains constant? c. If the frequency of a wave is doubled and if the speed remains constant, what is its wavelength? 6. A wave 0.5 meters long passes through a medium with a speed of 20 meters per second. What is the frequency of the wave? 7. What is the wavelength of a wave that has a speed of 0.8 m/s and a frequency of 100 Hz? 8. What happened to the speed of the wave in the spring lab, when you increased the tension in the spring? A \\M m 9. What is the frequency of a wave if the period is 0.2 seconds
