A sound wave has a frequency of 440 Hz and travels through air at 340 m/s.
(a) Calculate the wavelength of the sound wave.
(b) Explain what is meant by the term coherent sources in the context of wave interference.
(c) Two coherent sources emit sound of the same frequency. The sources are in phase and are 1.5 m apart. A detector is moved along a line parallel to the line joining the sources, at a perpendicular distance of 4.0 m from the midpoint. State the condition for constructive interference at a point on the detector line.
