When light from the sun enters the Earth's atmosphere, the air molecules act like tiny optical tuning forks that scatter the light in all directions. This scattering affects the way we perceive the color of the sky. Blue light has a shorter wavelength and higher frequency than other colors in the visible spectrum, making it more easily scattered by the air molecules. As a result, we see a blue sky during the day. This phenomenon is known as Raleigh scattering.
