# Single and double slit diffraction formulae

## Main Question or Discussion Point

Is the formula for single slit diffraction $$Dsin\theta = m\lambda$$ identical to the double slit diffraction besides m being minima rather than maxima? More specifically will m + 1/2 tell me the angles between maxima?
