Student question Time Left: 01:56:37 A stretched wire of length L, diameter d and volume density p is under tension F. The wire vibrates in its fundamental mode at a frequency of 400 Hz. Determine the fundamental frequency of a wire of the same material that is half as long, with twice the diameter and with four times the tension.
