A double slit is separated by a distance d and we shine two sources of light simultaneously on the slits. One has wavelength λ1 = λ and the other has wavelength λ2 =9/11λ. (a) What is the distance on the screen between the first bright fringes of each light source? (b) what are two smallest orders (m1 and m2 pairs) where the bright fringes from each source coincide?
