A pipe open at both ends resonates to a frequency ‘n1’ and a pipe closed at one end resonates to a frequency ‘n2’. If they are joined to form a pipe closed at one end, then the fundamental frequency will be ______.

(A)  (n_1n_2)/(2n_2+n_1)

(B) (2n_2n_1)/(2n_2+n_1)

(C) (2n_2n_1)/(n_1+n_2)

(D) (n_2+2n_1)/(n_1n_2)

#### Solution

(a) (n_1n_2)/(2n_2+n_1)
