Have you ever wondered why the sky is blue, the color that lifts our spirits whenever we look at it?
The primary reason the sky appears blue is due to a physical phenomenon called Rayleigh scattering.
The shorter the wavelength of the light, the stronger the scattering.
Additionally, the scattering of sunlight becomes more noticeable when it reaches the upper layers of the atmosphere.
The ozone layer, in particular, absorbs most of the violet light's short wavelengths, significantly preventing violet light from reaching our eyes. This is why the sky appears blue during the day.
So, why does the sky turn red, orange, or pink during sunrise and sunset?
At these times, the shorter wavelength lights like violet are completely scattered, leaving only the longer wavelengths—red, orange, and yellow—to reach our eyes. This creates those breathtaking views we see at sunrise and sunset.
The blue color of the sky can be explained by the interaction between sunlight and the gases and particles in the atmosphere, where shorter wavelengths scatter more.
The structure of the atmosphere and how our eyes perceive light are the factors that complete this visual spectacle.
