SUPERPOSITION OF WAVES Activity 2: Problem Solving Directions: Answer the following word problems by applying what you have learned in lesson 2. Show your complete solution by following the G-R-E-S-A format. 1. Gabby has created a standing wave by tying one end of the rope to a tree and motioning back and forth 60 times per second. 6 1 m A. How many complete waves can you trace? B. Can you tell from the picture what the wavelength is? C. What is the amplitude of the wave? D. How many times the fundamental is this standing wave? E. If the frequency that produced this wave is 60 Hz, what is the fundamental frequency? F. What is the velocity of the wave? 2. The string at the right is 1.5 meters long and is vibrating as the first harmonic. The string vibrates up and down with 33 cycles in 10.0 seconds. Determine the frequency, period, wavelength and speed for this wave. 3. A guitar string resonates at a frequency of 500 Hz forming a standing wave pattern with 5 loops. What is the fundamental frequency? 4. A stretched string of length 8 m vibrates at a frequency of 50 Hz producing a standing wave pattern with 4 loops. What is the speed of wave
