    phase difference=(2pi/(lambda)) * distance between two points
    therefore answer is (2pi/(340/160))*1 which is C

    but to find wavelength we use speed/frequency. so why in this question opposite is happening.

    find the wave length of the wave using wavelegth= speed/frequency, then divide 1 metre by the wavelength. multiply what you got with 2 pi.
