Dear Student,

◆ Answer - (2)

f' = 200 Hz

● Explanation -

Fundamental frequency of closed pipe is -

f = v/4l

Fundamental frequency of open pipe is -

f' = v/2l

f' = 2(v/4l)

So that,

f' = 2f

f' = 2 × 100

f' = 200 Hz

Hence, fundamental frequency of the open pipe is 200 Hz.

Thanks dear. Hope this is helpful to you..
