(a) Find the speed of transverse waves on the wire. m/s (b) Find the wavelength of the fundamental Find the frequency of the fundamental. Hz (d) Find the frequency of the second harmonic. (e) Find the trequency of the third harmonic. -16.66 points Tipiens 16 P.0s9 Astring with a mass density of 3.9 x 10-3 kg/m is under a tension of 31SNand is fixed at both ends. one of its reson (a) What is the fundamental frequency of this string? (b) Which harmonics have the given frequencies? (Enter 1 for the first harmonic, 2 for the second harmonic, etc 450 Hz

Explanation / Answer

(A) linear mass density. mu = m/L = (4.70 x 10^-3 kg)/(1.80 m)

= 2.61 x 10^-3 kg/m

v = sqrtp[ T / mu ] = 608 m/s

(B) wavelength = 2 L = 3.60 m

(C) f = v / wavelength = 169 Hz

(D) wavelength = L = 1.80 m

(E) f = 608/ 1.80 = 338 hz
