Two loudspeakers are placed on a stage 5.4 m apart and are radiating the same frequency, in phase. An observer walks along a line parallel to the loudspeakers and 12.7 m from them. Starting from the central point of the line (equidistant from the two loudspeakers) she observes that, as she walks, the sound intensity first decreases and then increases to a maximum again when she has travelled 1.4 m.  a. Explain this observation.

Stretched string

A stretched string is a wire which is made up of any metal that must have a larger length compared to its thickness. The ends of the wire are fixed, and when they oscillate or are plucked, it produces two reflected transverse waves of the same frequency and same amplitude. The waves or pulses are traveling in alternate directions and superimpose with one another. This waveform is named standing or stationary waves.
