Sound with frequency 500 Hz moves through a tube. This tube splits into two paths, with some of the sound taking the upper path (semicircle) and the rest of the sound taking the lower path. The sound then merges before it reaches the detector. Find the three smallest values of L for which the detected sound will be minimized.
