Why the colour of sky appears blue even though thewavelength of blue is greater than violet?
Answers
Answer:
Although violet has shortest visible wave length, the spectrum of light emission from the sun is not constant at all wave lengths and additionally is partially absorbed by the high atmosphere, So there is less violet in the light. Human eyes are also less sensitive to violet than blue. That's why sky is blue and not violet even though violet has shorter wave length.
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
