An open pipe has a piston inserted into one of its ends. A tuning fork with the frequency of 342 Hz is sounded at the open end of the pipe. At the same time, the piston is set in motion along the length of the pipe. It is observed that the air column in the pipe resonates when its length is 243.9 mm and then again when it's length is 745.6 mm. Calculate the end correction for this pipe and give your answer in mm.

End correction is a concept used to ensure proper resonance frequency results and to avoid any error in calculating the resonant frequency end correction is added to the length-Use the formula for end correction for pipe open at one end-e = (L2 - 3L1)/2Where L2 is 745.6L1 is 243.9
