1for point p s2p=√D2+d2
s1p=D
sub
√D2+d2-D
D√1+d2/D2-D
as d<<<<D
=D(1+d2/2D2)-D
hence d ans[1]

33wahi to... s1o and s2o are equal so whats the matter of refractive index there
1
24mera ans abhi bhi match nahin kar raha,,,,,,,,koi plz soln post karega.....
24ok..............iska matlab main aise hi do dino se dimag kharaab kar raha thaa...........[3][3]
33Eureka mai kah raha tha ki for O it doesnot matter what is refractive index between slit and screen
1i m absolutely right i m damn sure . maine abhi point p ke liye nikala same ans aa raha hai
24question mein mentioned to hai..........ki point O par phase diff nikalna hai
24@ richa....ans in post11 are books answer.....i am not getting those d2/2D terms.....
@ abhishek.i cant get ur point
24Ans1 2Ï€/λ [√d2+xo2-x0+(μd2/2D)]
Ans2 2Ï€/λ [μ√d2+xo2-x0+(d2/2D)]
24@ sky.......i followed ur method but my answer is not matching.....
24ya..........
plz post complete soln if u have some time.....[1][1]
otherwise i am still trying to force the answer.......
1ok then work out ...
first calculate the geometrical distance.
then multiply μ wherever required to get the optical distance.
delXG = [S S1 + S1 O] - [SS2 + S2O ]
THIS IS THE GEOMETRICAL DIST..
now find opt dist by multiplying mu in two places as given in diff questions...
then use the formual : Δθ= Δx.2Π/λ
24but i assumed them to be d and distance b/w sli and screen to be D
