Question
What is the color of sunlight?
- Red
- White
- Green
- Yellow
Hint:
The sun emits all colors of the rainbow
The correct answer is: White
We can observe on the paper that the sunlight is split into a spectrum of colours like a rainbow, every colour in VIBGYOR pattern i.e., violet, indigo, blue, green, yellow, orange and red can be seen.The color of the sun is white. The sun emits all colors of the rainbow more or less evenly and in physics, we call this combination "white"
