Unformatted text preview: mass per unit length µ1= 8 g/m and µ3= 2 g/m. You launch harmonic waves of frequency f=100 Hz from string 1 toward string 3. You want to make sure that all of the incident power you launch is transmitted to string 3 with no reflection on string 1, so you insert a piece of string of length L2 and mass per unit length µ2 between them. Assume a tension of 10 N. What should L2 and µ2 be in order that there be no reflected wave on string 1? 7. Wave interference. We’ve seen one example of wave interference: standing waves, which result from addition of waves of the same frequency and wavelength that travel in opposite directions. Let’s consider a second example of interference, resulting from addition of waves of the same frequency and wavelength that travel in the same direction. Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves wi...
