प्रश्न
When sunlight passes through water droplets in the atmosphere it gets dispersed into its constituent colours forming a rainbow. A similar phenomenon is observed when white light passes through a prism.
Instead of sunlight, a green-coloured ray is passed through a glass prism. What will be the colour of the emergent ray?

उत्तर
The colour of the emergent ray will be green. A prism does not change the colour of light. It simply disperses white light into its constituent colours.
