When does the doubleslit 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

Best ResponseYou've already chosen the best response.0the parts shaded in black are the darkest areas and the rest are lighter, but different shades of light if that makes sense haha :P

Best ResponseYou've already chosen the best response.1we have these two conditions: \[\begin{gathered} {\text{path difference = n\lambda }}{\text{,}}\quad {\text{bright regions}} \hfill \\ {\text{path difference = }}\left( {{\text{n + }}\frac{{\text{1}}}{{\text{2}}}} \right){\text{\lambda }}{\text{,}}\quad {\text{dark regions}} \hfill \\ \end{gathered} \]
