Question $1$

The intensity is calculated by taking the square of a wave's amplitude $(\backslash (\backslash$mathrm$\{$I$\}=|\backslash$mathrm$\{$A$\}(\backslash$mathrm$\{$x$\})|^\{2\}\backslash )).$ The intensity pattern for a double slit is shown below. Which intensity pattern best represents what would happen if the number of slits were increased and their spacing decreased? The scale for all four graphs is the same.

$($A$)$

$($B$)$

$($C$)$
