Question

Consider a double slit experiment.

1) For light of 650 nm, a distance d between two narrows slits of 0.08 mm, and a screen placed one meter away, what is the position of and angle to the first maximum, m=1, from the center.   Calculate both using the small angle approximation and exactly.

2) How would a +10 nm uncertainty on the wavelength made the position of the first maximum from the center vary.
