text: WHY DO WE SAY THE SKY IS BLUE?
text: If, for example, the Sun didn't output any blue light, the sky would not be blue because there would be no blue light to refract.
text: During daytime, the sky appears to be blue because air molecules scatter shorter wavelengths of sunlight more than longer ones (redder light).
