1. The problem statement, all variables and given/known data Two slits are separated by a distance of 4.40x10-6m and illuminated with two monochromatic light sources with wave lengths of 600nm (red) and 400nm (violet). The mr bright fringe of the red light coincides with the mv bright fringe of the violet light. What are the lowest possible values for mr and mv? d= 4.40x10-6 m λr = 600nm λv = 400nm mr = ? mv = ? 2. Relevant equations Δx/ L = λ/d xm = mLλ / d d sinΘm = mλ 3. The attempt at a solution I honestly don't know where to start as it seems i'm missing needed information for use any of the equations, but it is the last question of my assignment. Sorry if formatting is wrong, first time posting.
