Hi !
can any body help me in solving this problem!
The electric field at Poin P due to N slits is,
A(r,\theta,t) =A(r) \frac{\sin\frac{1}{2}\N\Delta\phi\cos(kr-\omega\ t)}{\sin\frac{1}{2}\Delta\phi}
where \Delta\phi =kd\sin\theta,
"d" being the spacing between adjacent slits.Let N=4.
a) Find two anglws on either side of \theta=0 at which there is an interference minima.
b)Find the spacing between the minima compare tp the case pf only two slits of separation "d".
I have solved its "a" part but i just couldnt solve its "b" part. Plz help mw in solving this:
Thanks a lot!
