Hi!
please help me in the following problem?
"The electric field at point P due to N slits is,
E (r, theta, t) = A(r) sin (N delta phi/2) cos(kr-wt)
_____________
sin (delta phi/2)
where delta phi=kdsin (theta) , "d" being the spacing between the adjacent slits. let N=4
(a) Find two angles on either side of theta=0 at which there is an interference minima.
(b) Find the spacing between the minima compare to the case of only two slits of separation "d".
Now i have solve its (a) part but i just can't solve its (b) part.
Can u please help me in this pleasezzzzzzzzzzzzzzzz.
Thanks in advance!
