In a Young's double-slit experiment, when $( \pi d / \lambda ) \sin \theta$ is a multiple of ( $\pi ( \pi , 2 \pi , 3 \pi )$ ), the intensity at the viewing screen
A) is a maximum.
B) is a minimum.
C) is halfway between the maximum and minimum.
D) cannot be determined (we need $d , \lambda , \text { and } \theta$ )

In Young's double-slit experiment, the condition for maximum intensity (constructive interference) is when the path difference is an integer multiple of the wavelength, which corresponds to $( \pi d / \lambda ) \sin \theta$ being a multiple of $\pi$.
