The sky appears blue due to a phenomenon known as Rayleigh scattering. This occurs when sunlight passes through Earth’s atmosphere, which contains gases and tiny particles. Sunlight, or white light, is made up of different colors, each with a different wavelength. Blue light has a shorter wavelength and is scattered more easily than colors with longer wavelengths, like red or yellow.
As sunlight interacts with the molecules in the atmosphere, the shorter wavelengths of blue light are scattered in all directions, making the sky look blue to our eyes. This scattering effect is stronger for blue light because of its shorter wavelength compared to other colors in the visible spectrum.
At sunrise and sunset, when the sun is lower in the sky, its light passes through more of Earth’s atmosphere, scattering even more of the shorter wavelengths and allowing the longer wavelengths, like red and orange, to dominate the sky’s color.
