Point source of light, opaque screen with hole. photodiode problem

[QUOTE="Simon Bridge, post: 5542868, member: 367532"] The argument seems reasonable given the assumptions ... ie. that m=1, and that the photodiode is approaching down the line through the point source and the center of the hole. You can increase your confidence levels by checking your assumptions. Since the detector is approaching from infinity, then the first max encountered will be the farthest from the screen. So how does d depend on m? For the second part. i1 and i2 are the intensities measured at the detector position right? Don't these also depend on the source intencities? ie. does all the light from the source pass through the hole? Is the hole really a point source (what path do light rays from the hole take to get to the detector)? [/QUOTE]
