Question

1. A string with a mass per length of 2.00 gm/m is stretched with a force of 120 N between two points that are 0.400 m apart. The fundamental frequency of the stretched string is in tune with the fundamental frequency of an organ pipe filled with air and open at both ends. The velocity of sound in air at 0 1.

Explanation / Answer

Part 1)

Apply v = f(wavelength) = sqrt(T/u)

(f)(.8) = sqrt(120)/.002

f = 306.2 Hz


For an open tube

v = f(wavelength)

331 = (306.2)(2L)

L = .541 m (54.1 cm)


Part 2)

The wavelength of the fundamental is 4L = 4(20) = 80 cm
