Why is the sky Blue? Fact of the Day!

 The sky appears blue to us because of a process called scattering. Imagine the sky as a giant, invisible bubble. When sunlight, which is made up of different colors, enters this bubble, it collides with molecules and tiny particles in the air. The  light then scatters or spreads out in different directions.

The blue color comes into play because sunlight is a mixture of colors. And each of these colors is associated with a different wavelength. Some colors, like red, orange, and yellow, have longer wavelengths. Others, like blue and violet, have shorter wavelengths. During the scattering process, colors with shorter wavelengths get scattered more than those with longer ones. That's why we see a blue sky instead of a red, orange, or yellow one.
