Question

A rose appears red in white light. How will it appear in green light? Give a reason for your answer.

Answer 1

Reason -

1. If a red rose is seen in green light, it appears black. The reason is that the rose absorbs the green light falling on it and reflects none.
2. As we know that if an object absorbs all colours, it will appear black and if an object does not absorb any colour, it will appear white in colour.
3. Hence, If a rose appears red in white light, it will appear black in green light.
