Two speakers connected to the same source of fixed frequency are placed \( 2 \mathrm{~m} \) apart in a box. A sensitive microphone placed at a distance of \( 4 \mathrm{~m} \) from the mid-point along the perpendicular bisector shows maximum response. The box is slowly rotated till the speakers are in line with the microphone. The distance between the midpoint of the speakers and the microphone
P remains unchanged. Exactly, 5 maximum responses (including the initial and last one) are

W. observed in the microphone in doing this. The wavelength of the sound wave is
(a) \( 0.8 \mathrm{~m} \)
(b) \( 0.5 \mathrm{~m} \)
(c) \( 0.2 \mathrm{~m} \)
(d) \( 1.6 \mathrm{~m} \)
