A) v
B) 2v
C) v/2
D) 3v/4
Correct Answer: A
Solution :
For cylindrical tube open at both ends frequency \[v=\frac{v}{2l}\] When half of tube is immersed in water, its length will be half and also it will behave as a closed pipe. \[\therefore \,\,\,\,\,\,\,\,\,\,\,\,\,\nu '=\frac{v}{4(1/2)}=\frac{v}{2l}\,\,\,\,\,\,\therefore \,\,\,\,\,v'=v\]You need to login to perform this action.
