B) Primary rainbow is a real image and secondary rainbow is a virtual image
C) Both primary and secondary rainbows are virtual images
D) Both primary and secondary rainbows are real images
Correct Answer: C
Solution :
The rainbow is seen as a virtual image in the form of a coloured arc centered on the anti-solar point that is the point below the horizon, directly opposite the sun in the sky. When conditions are favourable two rainbows are seen the brighter is the primary and a fainter second one with the colours reversed. Hence, both primary and secondary rainbow are virtual images.
