Why is it blue and not some other color? There's actually a scientific explanation for this! Let's explore together.👇
The light coming from the Sun appears white, but in fact, white light contains all the colors we see in a rainbow. These colors have different wavelengths. As sunlight passes through the Earth's atmosphere, it encounters small particles like air molecules, dust, and water droplets. These interactions cause the light to scatter, meaning it spreads out in different directions.
Since blue and violet have shorter wavelengths, they scatter much more than longer wavelength colors like red and yellow. However, there are a few important reasons why the sky appears blue and not violet. First, our eyes perceive blue much better than violet. Second, violet light scatters even more in the atmosphere, making blue the dominant color we see.
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.
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 structure of the atmosphere and how our eyes perceive light are the factors that complete this visual spectacle.
