1.	The fundamental frequency of an open organ pipe is 300Hz. The first overtone of this has same frequency as that of first overtone of a closed organ pipe. If speed of sound is 330m/s, then the length of closed of organ pipe will beA. 41cmB. 37cmC. 31cmD. 80cm
Answer» Correct Answer - A (The frequency of first overtone of open pipe ) = (The frequency of first overtone of a closed pipe) `2n_0 = 3n_c` `2xx300=3xxn_c` `therefore n_c=200Hz` `therefore n_c=(v)/(4l_c)` `therefore l_c =(v)/(4n_c) = (330)/(4xx200) = 41.25cm`
