Question

A leaf will appear green in sunlight, what is its colour in red light?

Answer 1

1. A green leaf will appear green because it will reflect only green light.
2. Yellow light is the combination of red and green light.
3. So yellow light will reflect red and green light.
4. When the green leaf is placed in yellow light, the leaf absorbs red light from yellow and reflects green light.
5. Hence, a green leaf will appear green in yellow light.
