Question: What factors affect the wavelength, speed, and power of waves? 1. Record: The speed of a wave is the distance a wave pulse travels per second. The wave speed is displayed below the spring. Click Play. What is the wave speed? 2. Experiment: The wavelength and speed of a wave can be influenced by many factors. Adjust the amplitude, frequency, tension, and density as described in the table below. Then report whether this causes the wavelength and wave speed to increase or decrease. Return each variable to its original value after each experiment. Adjustment Effect on wavelength Effect on wave speed Increase amplitude Increase frequency Increase tension Increase density 3. Analyze: Click Reset. Set the Frequency to 0.80 Hz, Tension to 2.0 N, and Density to 2.0 kg/m. Click Play, and then click Pause. Turn on Show rulers. A. What is the wavelength? B. What is the wave speed? C. How are the wavelength, frequency, and wave speed related? In general, the wave speed (v) can be calculated from the frequency (f) and wavelength () using the formula v = f . A. D. What is the wavelength of a wave with f = 0.9 Hz and v = 154.9 cm/s? To check, set Frequency to 0.90 Hz, Tension to 2.4 N, and Density to 1.0 kg/m. E. Change the Density to 1.5 kg/m, and click Play. Based on the wave speed, what do you expect the wavelength to be? Measure the wavelength to check
