1. The problem statement, all variables and given/known data A single slit forms a diffraction pattern with monochromatic light. The 6th minimum of the pattern occurs at an angle of 23° from the central maximum. The number of bright bands on either side of the central band is closest to: A) 16 B) 13 C) 14 D) 15 E) 17 2. Relevant equations asin(theta)=mlambda 3. The attempt at a solution Honestly I have no idea how to do this. Using the data given, I can only set up one equation with 2 unknowns, which is impossible to solve. On top of that I am unable to deduce a relationship between maxima and minima in a single-slit diffraction. I hope someone would throw me some light on this, thanks!
