hi friends , tell asimple answer... why the sky is blue ?
Answers
Here is your answer.....
The reason the sky is blue is because of three simple factors put together: that sunlight is made out of light of many different wavelengths, that Earth’s atmosphere is made out of molecules that scatter different-wavelength light by different amounts, and the sensitivity of our eyes. Put these three things together, and a blue sky is inevitable. Here’s how it all comes together.
Sunlight is made up of all the different colors of light… and then some! The photosphere of our Sun is so hot, at nearly 6,000 K, that it emits a wide spectrum of light, from ultraviolet at the highest energies and into the visible, from violet all the way to red, and then deep into the infrared portion of the spectrum. The highest energy light is also the shortest-wavelength (and high-frequency) light, while the lower energy light has longer-wavelengths (and low-frequencies) than the high-energy counterparts. When you see a prism split up sunlight into its individual components, the reason the light splits at all is because of the fact that redder light has a longer wavelength than the bluer light.
Hope it helps !!!
the blue color of the sky
----------------------------------------------------------------------------------------
The color of the sky is due to the property of dispersion of light the white light of the color before reaching the earth's surface gets dispersed into its 7 components VIBGYOR the molecules present in the atmosphere are capable of scattering only the light with the shortest wavelength and hence red light won't get scattered
As the light that we get from sun is white in color and due to atmospheric refraction splitting up of white light takes place and the light with the longest wavelength gets lost in the space and blue and violet has the shortest wavelength but the intensity of blue will be much more than that of violet which makes us see the sky blue in color and our eyes are more sensitive to blue light
