Question: IP The interference pattern shown in the figure is produced by green light with a wavelength of ? = 505 nm passing through two slits

IP The interference pattern shown in the figure is produced by green light with a wavelength of ? = 505 nm passing through two slits with a separation of 122 ?m . After passing through the slits, the light forms a pattern of bright and dark spots on a screen located 1.15 m from the slits.

Part A

What is the distance between the two vertical, dashed lines in the figure (a)?

Part B

If it is desired to produce a more tightly packed interference pattern, like the one shown in the figure(Figure 1) (b), should the frequency of the light be increased or decreased?
