A steel wire in a piano has a length of 1.35 m and a mass of 1.85 x 10² Kg. The wire must be stretched to a specific tension so that the fundamental vibration of a certain key is generated with a speed of sound 636 m/s as the distance from the nut to the bridge is 1.07 m. a. Calculate the tension. b. Calculate the fundamental frequency. c. Calculate the wavelength of the sound produced on the air.
