Pick the wrong answer in the context with rainbow. (a) An observer can see a rainbow when his front is towards the sun. (b) Rainbow is a combined effect of dispersion refraction and reflection of sunlight. (c) When the light rays undergo two internal reflections in a water drop, a secondary rainbow is formed. (d) The order of colours is reversed in the secondary rainbow.

Answer: (a). A rainbow is seen with the sun behind the observer, facing the rain drops, so (a) is wrong. (b), (c), (d) are correct facts about rainbows. So the answer is (a).
