Question

Can you help me with the problem below? Any help is appreciated!

A pair of narrow, parallel slits separated by 0.250 mm are illuminated by the green component from a mercury vapor lamp (ë = 546.1 nm). The interference pattern is observed on a screen 1.20 m from the plane of the parallel slits. Calculate the distance (a) from the central maximum to the first bright region on either side of the central maximum and (b) between the first and second dark bands in th interference pattern.


You will find the equations you need to use here:
http://en.wikipedia.org/wiki/Double-slit_experiment
or many other websites that dseal with Young's double slit experiment. I suspect it is also in your text material.

Use n = 0 for the position of the central maximum.

We will be happy to critique your work.
