Fringe spacing \(\Delta y\) as a function of screen distance \(L\) for two different slides.
Fringe spacing \(\Delta y\) as a function of screen distance \(L\) for two different slides.
In an experiment, light from a single monochromatic laser of wavelength \(\lambda\) passes through a double slit and forms an interference pattern on a distant screen. The experiment is performed using Slide 1 and then repeated using Slide 2, each having a different slit separation. For each slide, the distance \(L\) between the slits and the screen is varied, and the adjacent bright fringe spacing \(\Delta y\) is measured, producing the linear graphs shown.

Which of the following statements correctly compares the two slides based on the graphical evidence?
