The Colour Of The Sky

The Colour Of The Sky

Why is the Sky Blue?

Some say it's due to the blue oceans.

Some think it's what's in the atmosphere(mostly nitrogen and oxygen).

Some believe it's because outer space is blue.

But truthfully, it has to do with the size of the particles in the Earth's atmosphere. They are considered "small" particles (much less than 1 nanometer across).

These small particles scatter sunlight as it passes through.

The Light Of The Sun

The Light Of The Sun

Sunlight contains all visible colours of light and more.

In the 1870s, a man named Rayleigh found that each colour (or wavelength) of light is scattered to a different degree.

More blue light than other colours is scattered out of the sunlight travelling through the atmosphere.

This creates a diffuse blue glow and makes the sun appear yellow in colour.

Evening Time: Yellow And Red

Evening Time: Yellow And Red

When the sun is lower in the sky, sunlight travels a longer distance through the atmosphere to reach an observer.

This means it encounters more particles that scatter out most of the blue light, as well as some green and yellow light. This leaves mostly red light when the sunlight reaches the observer.
