A double$-$slit interference experiment is performed with two very narrow slits serarated by $0\mathrm{.}16$mm$.$ The experiment uses red light with a wavelength of $700$nm and projects the interference pattern onto a screen $7\mathrm{.}0$m away from the slits. $($a$)$ What is the distance between two nearby bright fringes on the screen? $($b$)$ What is the distance between two nearby dark fringes on the screen? Assume these fringes are all near theta$=0.$
