![]() The interference between incident and reflected waves produces a standing wave. ![]() The incident and reflected wave have the same frequency and amplitude but travel in opposite directions along the string. Incident wave traveling to the other end of the string will reflect back. While the wave vibrator continuously generates harmonic waves, the Standing waves are formed on a stretched string for a group of resonant frequencies in this experiment. The displacement of every element on the string is at a right angle to the direction of propagation of the wave such a traveling wave is referred to as a transverse wave. Although the wave generated by the wave vibrator propagates along the string, every element on the string oscillates up and down while the wave passes through it. ![]() In this experiment, transverse waves are generated along the stretched string. When a wave vibrator is attached to the stretched string and moves up and down in simple harmonic motion, s continuous wave on the string will have the shape of a sine or cosine curve such a wave is called a harmonic wave. Harmonic waves are generated on a stretched string in this experiment. Instead, the medium such as a string, spring, water, or atmosphere, oscillate back and forth or up and down about their equilibrium position. Although the wave carries energy from one place to another, the medium is not carried with the wave but allows the wave to pass through it. Discussion A wave is a disturbance that propagates through space. Figure 1: Physical lab's experimental set-up. ![]() Measure the first four harmonics on the string. Compute the speed of the wave on the string. Phys 1401 Experiment 11: Standing Waves on a Stretched String Objectives When you have completed this assignment, you will be able to: 1.
