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 ms-1 -
B.
264 ms-1 -
C.
132 ms-1 -
D.
66 ms-1
Correct Answer: Option B
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.
