The wave length of sound emitted by a source is\[1.7\times {{10}^{-2}}m\]. Calculate the frequency of the sound if its velocity is\[\text{343}.\text{4 m}{{\text{s}}^{-\text{1}}}\].

Answer:

We know, \[V=n\lambda \] \[\Rightarrow \]\[n=\frac{V}{\lambda }=\frac{343.4}{1.7\times {{10}^{-2}}}\] \[=2.0\times {{10}^{4}}Hz\]
