(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A double slit is composed of two single slits. Each slit has a width of w = 0.01 mm and they are spaced s = 0.04 mm apart. Because the double slit is actually two single slits, the single slit diffraction pattern is superimposed over the double slit pattern and so some of the double slit maxima are missing because they overlap with single slit minima. Find the number (m) of the first missing maximum in the double slit pattern.

2. Relevant equations

wavelength = (y_{m}/m)(s/l)

3. The attempt at a solution

s = 0.04 mm

w=0.01 mm

I am completely lost on this one. I know I need the wavelength to find this answer along with the maxima value (y_{m}) and a value for L. could you please help me get started?
