Question-13.4 When a diffrcction pottern occurs due to double slit interterence, the central bright spot is atm=0, with subsequent bright spots oppearing at integor values m=1,2,3. If a slit pair is separated by 0.0Imm, but is illuminated by two separate light sources at wavelengths of 400nm and 700nm, what is the distance botween the bright fringes represented by m=4 for both light sources when projocted onto a screen a distance of 8.2m from the slit pair? Put your answer in mm and give units
