Oct 11, 2024 · Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Closer to the horizon, the sky fades to a lighter blue or white.
The Appearance of the Sky. The colors we see in the sky come from sunlight that is scattered by molecules in the atmosphere. This process is called Rayleigh scattering. Nitrogen and oxygen make up most of the molecules in our atmosphere, but any gas or aerosol suspended in the air will scatter rays of sunlight into separate wavelengths of light.
Sep 11, 2024 · Visible light includes the wavelengths our eyes can see. The longest wavelengths we can see look red to us. The shortest wavelengths we can see look blue or violet. The wavelengths in this picture are not to scale. A red light wave is about 750 nanometers, while a blue or violet wave is about 400 nanometers. A nanometer is one-billionth of a meter.
1:13. The lights we see in the night sky are in actual fact caused by activity on the surface of the Sun. Solar storms on our star's surface give out huge clouds of electrically charged particles. These particles can travel millions of miles, and some may eventually collide with the Earth.
Nov 4, 2023 · Even though violet light is scattered too, there are a couple of reasons why we see the sky as more blue than purple, according to Ed Bloomer, an astronomer at the Royal Observatory Greenwich in ...
Aug 25, 2022 · The answer lies in the physics of when sunlight passes through the atmosphere. The light rays are scattered in all directions as they hit the air molecules, and light at the blue end of the ...
