When does the double-slit interference have its first dark spot on either side of the central peak intensity? **will draw image!** A. when the paths d_1 and d_2 differ by one wavelength B. when the paths d_1 and d_2 differ by half a wavelength C. when the waves arrive in step, or "in phase" with each other D. when the paths d_1 and d_2 have the same length

    we have these two conditions: \[\begin{gathered} {\text{path difference = n\lambda }}{\text{,}}\quad {\text{bright regions}} \hfill \\ {\text{path difference = }}\left( {{\text{n + }}\frac{{\text{1}}}{{\text{2}}}} \right){\text{\lambda }}{\text{,}}\quad {\text{dark regions}} \hfill \\ \end{gathered} \]

    \[\begin{gathered} {\text{path difference = }}n\lambda ,\quad {\text{bright regions}} \hfill \\ {\text{path difference = }}\left( {n + \frac{1}{2}} \right)\lambda {\text{,}}\quad {\text{dark regions}} \hfill \\ \end{gathered} \]
