Title : Why Is the Sky Blue? | Wave Theory Explained Description : Have you ever wondered why the sky appears blue? In this video, we explore the fascinating science behind light scattering and ... So, in short, the sky is blue because of Rayleigh scattering, which causes shorter blue wavelengths of light to scatter more than other colors. Our eyes are tuned to see blue more clearly, and the Sun emits more blue than violet light, which is why our daytime sky isn’t purple. The sky is blue and sunsets are red because different colors of light behave differently when they encounter air molecules, known as Rayleigh scattering. The sky appears red because small particles of dust, pollution, or other aerosols also scatter blue light, leaving more purely red and yellow light to go through the atmosphere.
