1. The problem statement, all variables and given/known data Surprisingly, large interference effects can occur even when one of the interfering sources is not very probable. In the two-slit interference experiment, if one slit is “stopped down” so that the intensity of the wave getting through is reduced by a factor of 100 (relative to the other slit), show that the intensity maximum of the pattern is still (roughly) 50 per cent higher than at a minimum. 2. Relevant equations [tex]\psi[/tex]2 = A*ei(kr1 - wt) [tex]\psi[/tex]1 = A*ei(kr2 - wt) 3. The attempt at a solution I'm assuming that we add the 2 wave equations to find [tex]\psi[/tex]total. Since 1 slit has 1/100 the intensity of the other and since I is proportional to A2 then the amplitude of reduced-intensity wave would have A= 1/10000?
