Intensity pattern for the two-slit barrier with slit spacing d.
Intensity pattern for the two-slit barrier with slit spacing d.
A monochromatic laser beam of wavelength \(\lambda\) is incident normally on a barrier containing two narrow slits separated by a center-to-center distance \(d\). The resulting light intensity pattern observed on a distant screen is shown in the graph, where \(y\) is the position along the screen and \(y_1\) is the location of the first-order principal maximum. The two-slit barrier is then replaced with a four-slit barrier having the exact same slit width and center-to-center slit spacing \(d\). Which of the following graphs best represents the new light intensity \(I\) on the screen as a function of position \(y\)?
