उत्तर
A red rose is seen in green light. It will appear black.
Explanation:
A red rose is seen in green light. It will appear black. This is because a red object reflects red light and absorbs other colours. Since green light contains no red wavelengths, the rose absorbs all the green light and reflects none, making it appear black.
