7. The blue colour of sky is due to A.Reflection of sunlight B.Refraction of sunlight C.Scattering of shorter wavelengths of sunlight in the atmosphere D.Scattering of longer wavelengths of sunlight in the atmosphere
Option C Solution: Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Closer to the horizon, the sky fades to a lighter blue or white.
