Answer 2

Answer:

BLUE

Explanation:

1. The white light coming from the Sun is really made up of all the colors of the rainbow. We see all those colors when we look at rainbows. Raindrops act as tiny prisms when lit by the Sun, bending light and separating it into its different colors.
2. The light you see is just one tiny bit of all the kinds of light energy beaming around the Universe - and around you! Like energy passing through the ocean, light energy travels in waves, too. What makes one kind of light different from others is its wavelength - or range of wavelengths. 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.
3. 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. A human hair is about 50,000 nanometers thick! So these visible light wavelengths are very, very tiny.
5. Another important thing to know about light is that it travels in a straight line unless something gets in the way to
7. reflect it (like a mirror)
8. bend it (like a prism)
9. or scatter it (like molecules of the gases in the atmosphere)
10. As the white light from the Sun enters Earth’s atmosphere, much of the red, yellow, and green wavelengths of light (mixed together and still nearly white) pass straight through the atmosphere to our eyes. The blue and violet waves, however, are just the right size to hit and bounce off of the molecules of gas in the atmosphere. This causes the blue and violet waves to be separated from the rest of the light and become scattered in every direction for all to see. The other wavelengths stick together as a group, and therefore remain white.
