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.
- 528 ms-1
-
264 ms-1
- 132 ms-1
- 66 ms-1
The correct answer is: B
Explanation
in a vibrating string the fundamental frequency is given by fo = v/2Ltherefore velocity = 2L x f.
= 2 x 0.6 x 220
= 264 m/s.
