In a long cylindrical tube an air column is constructed by fitting a movable piston A tuning fork of frequency 416Hz sends longitudinal sound waves Consider the speed of sound in the air as 333m s It is observed that the air column in the tube vibrates in its fundamental frequency How far from the open end should the piston be in this situation A 10cm B 20cm C 30cm D 40cm
