The atmosphere is the mixture of gas molecules and other materials surrounding the Earth. We think of it as a thick layer encircling our planet, but astronauts call it the "thin blue line" because from space, it appears narrow and delicate. The atmosphere is made mostly of the gases nitrogen (78%), and oxygen (21%). Argon gas and water (in the form...
Light is a kind of energy that radiates, or travels, in waves. Many different kinds of energy travel in waves. For example, sound is a wave of vibrating air. Light is a wave of vibrating electric and magnetic fields. Electromagnetic Waves It is one small part of a larger range of vibrating electromagnetic fields. This range is called the electromag...
Visible light is the part of the electromagnetic spectrum that our eyes can see. Light from the sun or a light bulb may look white, but it is actually a combination of many colors. We can see the different colors of the spectrum by splitting the light with a prism. The spectrum is also visible when you see a rainbow in the sky. The colors blend con...
Light travels through space in a straight line as long as nothing disturbs it. As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or a gas molecule. Then what happens to the light depends on its wave length and the size of the thing it hits. Dust particles and water droplets are much larger than the...
The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air. However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different...
On Earth, the sun appears yellow. But what if you were out in space? What color would it be? Read More →
5 days ago · Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
