An open pipe resonates to a frequency f_(1) and a closed pipe resonate

1.	An open pipe resonates to a frequency f_(1) and a closed pipe resonates to a frequency f_(2). If they are joined together to form a longer tube, then it will resonate to a frequency of (neglect end corrections)
Answer» `(f_(1)f_(2))/(2f_(2)+f_(1))` `(f_(1)f_(2))/(f_(2)+2f_(1))` `(2f_(1)f_(2))/(f_(2)+f_(1))` `(f_(1)+2f_(2))/(f_(1)f_(2))` ANSWER :A
