(adsbygoogle = window.adsbygoogle || []).push({}); 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*e^{i(kr1 - wt)}

[tex]\psi[/tex]1 = A*e^{i(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 A^{2}

then the amplitude of reduced-intensity wave would have A= 1/10000?
