Why is the sky is blue?
Oh, I remember reading about that in school. Can you explain it to me again?
Of course! Essentially, as sunlight enters the Earth's atmosphere, it collides with particles like nitrogen and oxygen. These collisions cause the light to scatter in all directions. Blue light has a shorter wavelength and scatters more easily than other colors, so it ends up being the dominant color that we see in the sky.
