1. The problem statement, all variables and given/known data
Laser light is projected into two small slits that are 1mm apart. The fringe pattern on the screen is missing the 4th bright fringe. That is, there is a bright center fringe and three more bright fringes to either side of the central bright fringe, but the 4th one is missing. For that matter, the 8th is missing too. What is the size of the slit(s)?
2. Relevant equations
asinΘ=mλ
3. The attempt at a solution
