¿Por qué es azul el cielo?

The video explains why the sky is blue, starting with the concept of white light, which is composed of various colors. When sunlight passes through a prism, it splits into a spectrum of colors, each with different wavelengths. Red light has the longest wavelength, while violet has the shortest. Blue light, with its intermediate wavelength, is scattered by the gases in Earth's atmosphere, primarily nitrogen and oxygen. This scattering effect, known as Rayleigh scattering, causes the sky to appear blue to our eyes.
