In the shown fig. S1 and S2 are two identical coher- ent sources of sound, separated by a distance d. A receiver moves along the line XY (which is parallel to line S1 S2) to detect the intensity of sound at various points on the line. Distance of line XY from line S1 S2 is D (gt gt d) . Point O is the foot of perpendicular bisector of the line S1 S2 on XY. Distance of first intensity maxima (on line XY) measured from O is y. Find percentage change in value of y if the temperature of air increases by 1%.
