When using 690 nm light to perform the double slit experiment, the interference in the middle is a bright fringe (constructive interference).
1. If the slits are 2.48 µm apart, at what angle will we observe the first-order dark fringe?
2. If we were able to observe the second-order bright fringe, at what angle would we expect it to be observed?
