In a \[YDSE\]experiment two slits \[{{S}_{1}}\]and \[{{S}_{2}}\]have separation of\[d=2mm\]. The distance of the screen is\[D=8/5m\]. Source S starts moving from a very large distance towards \[{{S}_{2}}\]perpendicular to \[{{S}_{1}}{{S}_{2}}\] as shown in figure. The wavelength of monochromatic light is 500 nm. The number of maximas observed on the screen at point P as the source moves towards \[{{S}_{2}}\]is\[3995+n\]. Find the value of n.
