A) \[1020\,\,m/s\]
B) \[920\,\,m/s\]
C) \[820\,\,m/s\]
D) \[720\,\,m/s\]
Correct Answer: D
Solution :
Here: length of column\[=40\,\,cm=0.4\,\,m\] Frequency of tuning fork\[=450Hz\] Using the formula\[n=\frac{v}{4l}\] or \[v=450\times 4\times 0.4=720\,\,m/s\]You need to login to perform this action.
