Question $10(5$ points$)$

Please refer to Figure $3,$ which shows the pattern of interference fringes for light of wavelength $612$ nm passing through two narrow slits, projected onto a screen a distance of $2\mathrm{.}77$ m away. The distance on the screen between the centers of two adjacent bright fringes is $1\mathrm{.}25$ cm $.$ What is the distance between the two slits?

$\backslash (1\mathrm{.}36\backslash$mathrm$\{$E$\}-04\backslash$mathrm$\{$~m$\}\backslash )$

$2\mathrm{.}45$E$-04$ m

$\backslash (1\mathrm{.}63\backslash$mathrm$\{$E$\}-04\backslash$mathrm$\{$~m$\}\backslash )$

$8\mathrm{.}16$E$-05$ m
