A violin string, fixed at both ends, is made to oscillate and a standing wave, with three antinodes, is created. Discover the wavelength of this wave if the length of the string is L. If the tension in the string is increased by a factor of four, what happens to the frequency assuming that the above wave-pattern is to be maintained?
