given
L = 1.4 m
v = 47.9 m/s
A)
lamda1 = 2*L
= 2*1.4
= 2.80 m
B) f1 = v/lamda1
= 47.9/2.8
= 17.1 Hz
C) lamda3 = 2*L/3 (second overtone = third harmonic)
= 2*1.4/3
= 0.933 m
D) f3 = v/lamda3 (second overtone = third harmonic)
= 47.9/0.933
= 51.3 Hz
E) lamda4 = 2*L/4
= 2*1.4/4
0.7 m
F) f4 = v/lamda4
= 47.9/0.7
= 68.4 Hz

Two identical guitar strings are stretched with the same tension between supports that are not the same distance apart. The fundamental frequency of the higher-pitched string is 380Hz, and the speed of transverse waves in both wires is 200 m/s. How much longer is the lower-pitched string if the beat frequency is 6Hz?
