Monochromatic light from a narrow slit illuminates two narrow slit 0.3 mm apart producing an interference pattern with bright fringes 1.5 mm apart on a screen 75 cm away. Find the wavelength of the light. How will the fringe width altered if (a) the distance of the screen is doubled and (b) the separation between the slits is doubled?
