A) \[175\]
B) \[350\]
C) \[525\]
D) \[700\]
Correct Answer: B
Solution :
Resonance tube is a closed organ pipe is having an air column of variable length. If the frequency of fork n, then speed of sound is given by \[v=2n({{l}_{2}}-{{l}_{1}})\] where \[{{l}_{1}}\] and \[{{l}_{2}}\] are length of air column. Given, \[n=500\text{ }cycles/s,\] \[{{l}_{2}}=52cm=52\times {{10}^{-2}}m\] \[{{l}_{1}}=17cm=17\times {{10}^{-2}}m\] \[\therefore \] \[v=2\times 500(0.52-17)\times {{10}^{-2}}\] \[\Rightarrow \] \[v=350m/s\]You need to login to perform this action.
