Hello ,(adsbygoogle = window.adsbygoogle || []).push({});

How r u .

i know the formula of SINGLE SLIT DIFFRACTION PATTERN but i don,t know the method ho to drive it.Can any GENIUS tell me the procedure to drive this equation.

DERIVATION starts in this manner:

let d the seperation b/w any two consecutive slits,D=(N-1)

r1 is the distance of first slit to point P on screen and similarly r2 is the distance of second slit from P and so on,then electric field at point P due to contribution from all N slits will be

E=A(r)cos(kr1-wt)+A(r)cos(kr2-wt)+....................A(r)cos(krn-wt)

can u tell me the next steps how to drive the equation

plz plz plz do reply
