The luminous border that surrounds the profile of a mountain just before sun rises behind it, is an example of (a) dispersion (b) total internal reflection (c) interference (d) diffraction

Answer: (d). Sunlight bends around the edge of the mountain into the geometrical shadow region. Bending of light around an obstacle is diffraction, which makes the edge glow. So the answer is (d) diffraction.
