A double slit is illuminated with white light, rather than monochromatic light. Consider the following statements about what is observed on the screen that registers the arrival of the light: (I) a white central fringe and no other bangs; (II) a dark central fringe and alternating white and dark bangs on each side of the central fringe; (III) a white central fringe and a series of colored and dark bangs on each side of the central fringe; (IV) a continuous band of colors with no dark bangs; (V) a dark screen because no constructive interference can occur; (VI) a fully illuminated screen with white light with decreasing intensity from the center. Which of these statements is true?

Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.
