If the Nigeria flag (green, white, green) is viewed in pure yellow light, which of the following set of colours would be observed on the flag?
Yellow light is a mixture of red and green light, so yellow will reflect both red and green light. This means that a yellow object will appear red under red light and green under green light. So, the green stripes on the flag will appear green under yellow light, as green is part of yellow. The white stripe will look yellow because it reflects all colors.
Thus, when viewed under pure yellow light, the Nigerian flag will show green, yellow, and green.
