a) What is the equation that gives the angles of interference maxima for a double slit setup? Make a sketch that identifies each variable in your equation
b) What is the equation that gives the angles of dark fringes for single slit diffraction? Again, make a sketch that identifies all variables in your equation
c) The expression for the first double-slit maximum("n=1") looks very similar to that for the first single slit minimum. Yet one answer describes a maximum, while the other describes a minimum. how can that be?
