Dissimilarity in lengths of two paths for sound travel

Reference no: EM13660239

A speaker generates a continuous tone of 440 Hz. In the drawing, sound travels into a tube that splits into two segments, one longer than the other. The sound waves recombine before being detected with a microphone. The speed of sound in air is 339 m/s. What is the minimum dissimilarity in the lengths of the two paths for sound travel if the waves arrive in phase at the microphone?
