In a modified YDSE the sources S of wavelength 5000 A oscillates about axis of setup according to the equation `y=0.5 sin(pi/6)t` where y is in millimeter and t in second. At what time ti will the intensity at P, a point exactly in front of slit `S_(1)` be maximum for the first time?

In young's double-slit experiment set up, sources S of wavelength 50 nm illumiantes two slits S_(1) and S_(2) which act as two coherent sources. The sources S oscillates about its own position according to the equation y = 0.5 sin pi t , where y is in nm and t in seconds. The minimum value of time t for which the intensity at point P on the screen exaclty in front of the upper slit becomes minimum is
