Question
If the speed of a transverse wave on a stretched string of length 1 m is 60 m−1, what is the fundamental frequency of vibration?
Advertisements
Solution
Length of a stretched string (L) = 1 m
Wave speed (v) = 60 m/s
Fundamental frequency (f0) of vibration is given as follows:
\[f_0 = \frac{v}{2L}\]
\[= \frac{60}{2} \times 1\]
\[ = 30 s^{- 1} = 30 \text{ Hz }\]
