A) \[f'=f\]
B) \[f'=4f\]
C) \[f'=2f\]
D) \[f'=\frac{f}{2}\]
Correct Answer: A
Solution :
For fundamental frequency of vibration of air column \[l=\frac{\lambda }{2}\] \[\Rightarrow \] \[\lambda =2l\] Frequency, \[f=\frac{v}{\lambda }\] \[\Rightarrow \] \[f=\frac{v}{2l}\] ??.(i) When tube is placed inside water with half length immersed in water thenYou need to login to perform this action.
