Explanation:
When she moved a distance of 1 m from mid point she observe first destructive interference due to two speakers
so we can say that path difference of sound due to two speakers will be equal to half of the wavelength
so path difference is given as
so it will be
now we know that
now frequency of sound is given as
Your answer will be (B) - intense pressure.
