If tension is maintained on a stretched string of length 0.6m; such that its fundamental frequency of 220Hz is excited. Determine the velocity of the transverse wave in the string.

A. 528 m/s.
B. 264 m/s.
C. 132 m/s.
D. 66 m/s.

Correct Answer:

Option B – 264 m/s.

Explanation

in a vibrating string the fundamental frequency is given by fo = v/2L
therefore velocity = 2L x f.
= 2 x 0.6 x 220
= 264 m/s.
