Two very small, identical speakers, each radiating sound uniformly in all directions, are placed at points S1 and S2 as shown in the diagram. The speakers are connected to an audio source in such a way that they radiate in phase, at the common wavelength of 2.00 m. Sound propagates in air at 338 m/s. a) b) Calculate the frequency of the sound. (2 marks) Point M, a nodal point, is 7.0 m from S and more than 7.0 m from S2. Find the least possible distance M could be from S2.
