Extracted text: (A) An end of a combined string has a linear mass density of 8.00 kg/m, whereas the second string has a density of 3.55 kg/m. If a vibration with a frequency of 15 vibrations is imparted to the first stringand and the tension in the string is 550 N, find the frequency, velocity, and wavelength of (a) the incident wave, (b) the reflected wave, and (c) the transmitted wave.
