You are walking around a large open field.the only objects nearby are two identical speakers set some distance apart, which are both producing sound, in unison with a wavelength of 4 m. as you wander around the field, you notice that at certain locations, the sound you hear is surprisingly loud, while at other is seems unusually quiet. you conclude that you are observing the effects of interference between the two sources of sound waves.indicate what sort of interference woud occur at that point. constructive interference, destructive interference or in between.8 m from each speaker.11 m from one speaker and 7 m from the other.10 m from one speaker and 8 m from the other11 m from one speaker and 14 m from the other20 m from one speaker and 12 m from the other13 m from one speaker and 19 m from the other19 m from one speaker and 14 m from the other
