Question

An open pipe has a fundamental frequency f. If it
is immersed in water upto half its original length,
5th overtone of the new pipe is
(1) 111
12)
101
(3) 5f​

Answer 1

Answer:

For open pipe in air, fundamental frequency:

f= 2/V

For the pipe closed at one end(dipped in water),fundamental frequency:

f 1= V/4(1)= V/4× 2l=V/2 1

∴f 1 =f
