it is said that sky is appearing blue due to this reason

If you check the link, look at the chart of the color sensitivity of the eye cone photoreceptors. Notice how the blue cone sensitivity drops as you move to higher frequency-shorter wavelength, towards the violet.
That is why.

The vision recptors in the rod and cone cells are photosensitive chemicals which undergo transformations form cis to trans. These chemicals are more sensitive to a particular wavelength than others due to the way their atoms bonded.
The sky appears blue because of a phenomenon called Rayleigh Scattering which scatters the blue light more.

violet has the shortest wavelength while blue has somewhat longer wavelength than violet hence blue scatters much more strongly and the eyes r more sensitive 2 it. another reason may b since blue is a primary colour the cones present in eyes respond to it in greater intensity than violet.

The blue light having the high panetrating capacity.

The human eye contain certain pigment like rodhopsin and idhopsin in which the rhodhopsin is highly sensitive to blue, also the blue light having high penetrating capacity than violate.

Reliegh's relation......
scattering of light directly proportional to 1/4th of wavelength............. blue color has shortest wavelength so max scatterin and sky appears blue to us.
