sky is blue .explain.
Answers
Answer:
Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light 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.
Explanation:
Like most curious people, you have probably asked at some time, “Why is the sky blue?” Or if you saw a beautiful sunset or sunrise, you might have asked, “Why is the sky red?”
It’s so obvious that the sky is blue, you might think the reasons would be just as obvious. They aren’t! Of all the colors of the rainbow, why blue?
Couldn’t the sky just as easily be green? Or yellow? When we see a rainbow, we do see green and yellow in the sky, as well as blue, violet, orange, yellow, red, and everything in between.
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.
But why are there different colors? 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.
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.
Another important thing to know about light is that it travels in a straight line unless something gets in the way to
reflect it (like a mirror)
bend it (like a prism)
or scatter it (like molecules of the gases in the atmosphere)
