Sound artistEllen Fullman(Links to an external site.)is testing out a long string performance instrument. This instrument consists of a 1mm diameter steel wire whose density is 7700kg/m3. It is stretched between two walls that are 10 meters apart with a resulting tension of 100N. Ellen can make this wire resonate at a specific frequency by connecting it to anelectromechanical device(Links to an external site.). What frequency must she vibrate the wire (in Hertz) so that the resulting transverse standing wave has three antinodes? Group of answer choices A. 9.65 Hz B. 19.29 Hz C. 38.58 Hz D. 77.16 Hz
