(D) For a pipe closed at one end,the fundamental frequency is given by $f_c = \frac{v}{4L} = 150 \ Hz$.This implies that $\frac{v}{L} = 150 	imes 4 = 600 \ Hz$.When the same pipe is open at both ends,the fundamental frequency is $f_o = \frac{v}{2L}$.Substituting the value of $\frac{v}{L}$,we get $f_o = \frac{600}{2} = 300 \ Hz$.For an open pipe,all harmonics are present,so the frequencies produced are integer multiples of the fundamental frequency: $f_n = n 	imes f_o$,where $n = 1, 2, 3, \ldots$.Thus,the frequencies are $300 	imes 1, 300 	imes 2, 300 	imes 3, \ldots$,which results in $300, 600, 900, 1200, \ldots \ Hz$.

The fundamental frequency of an air column in a pipe closed at one end is $150 \ Hz$. If the same pipe is open at both ends,the frequencies produced in $Hz$ are:
