The physics of wave interference. 1. Two pulses as shown below are approaching each other. When they are directly on top of each other, draw the resulting pulse. The physics of a standing wave pattern. 2. Standing waves are set up in a string by a source vibrating at 100.0Hz. Seven nodes are counted in a distance of 63.0cm (including one node at each of the ends). a. How many wavelengths must there be in the string? b. What is the wavelength of the waves in the string? c. What is the distance between each node? d. What is the speed of these waves
