A) 163.84 Hz
B) 400 Hz
C) 320 Hz
D) 204.8 Hz
Correct Answer: B
Solution :
For sonometer \[n\propto \frac{1}{l}\] \[\therefore \] \[\frac{{{n}_{1}}}{{{n}_{2}}}=\frac{{{l}_{2}}}{{{l}_{1}}}\Rightarrow \frac{256}{{{n}_{2}}}=\frac{16}{25}\] \[{{n}_{2}}=\frac{256\times 25}{16}\] \[=400Hz\]You need to login to perform this action.
