Monochromatic light falls on a double slit, creating a diffraction pattern on a screen. If the entire apparatus (light source, slits and screen) is now placed in an atmosphere of a gas with a greater index of refraction than air, what effect would this have on: - N, the number of maxima on the screen - x, the distance between the central and first maxima? ON decreases, x remains the same O N increases, x increases O N remains the same, x decreases ON decreases, x increases ON decreases, x decreases ON remains the same, x increases O N increases, x remains the same ON remains the same, x remains the same O N increases, x decreases
