1. The problem statement, all variables and given/known data A system consisting of 5-slit (completely identical) that the distance between their centres, d, is four times the width of a slit, b. Calculate the relation between the major maximum at the center and the next maximum (can be given that position of the maximum is between the two minima) 2. Relevant equations I = E0^2(sin^2(beta)/beta^2)*(sin^2(5gamma)/sin^2(gamma)) 3. The attempt at a solution Tried some stuff with finding out the two minima and receiving 3(lambda)/2b but then when placing it inside the equation I couldn't continue.
