Extra Problem 11:
A double slit with a spacing of 0.095 millimeters between the slits is 4.579 meters from a screen. If yellow light of wavelength 570 nm strikes the double slits, what is the separation (in millimeters) between the central bright band and the first bright band on either side of the central band?

Habits of an Effective Problem Solver
An effective problem solver by habit approaches a physics problem in a manner that reflects a collection of disciplined habits. An effective problem-solver...
- ... reads the problem carefully and developd a mental picture of the physical situation. If necessary, sketch a simple diagram of the physical situation to help you visualize it.
- ... identifies the known and unknown quantities and record in an organized manner, often times they can be recorded on the diagram itself; equates given values to the symbols used to represent the corresponding quantity (e.g., v = 3.00x108 m/s, λ = 554 nm, f = ???).
- ... uses physics formulas and conceptual reasoning to plot a strategy for solving for the unknown quantity.
- ... identifies the appropriate formula(s) to use.
- ... performs substitutions and algebraic manipulations in order to solve for the unknown quantity.
