1. The problem statement, all variables and given/known data A double slit apparatus is illuminated 730 and 558 nm wavelengths. They form a two-colored interference pattern on a measuring screen located at a distance of 2.28 m from the slits. The slit separation is 42 wavelengths of 730 nm light. (a) What order (m) intensity maximum for λ = 730 nm light occurs near a distance of y = 0.205 m away from the central zeroth order? (b) What order maximum for 558 nm light lies closest to this order? λ1=730 λ2=558 L=2.28 m=? d=42*730 2. Relevant equations mλ=dsinθ tanθ=y/L 3. The attempt at a solution tanθ=.205/2.28 θ=5.14 a) m=(dsinθ)/λ = 3.76 (4?) a) m=(dsinθ)/λ = 4.92 (5?) So did I get the slit separation right? Are my orders suppose to be decimal numbers and do I round up or down?
