1) The sky appears blue due to dispersion and scattering of white light from the Sun and the blue color scatters the most because of its small wavelength as compared to other colors in spectrum.
2) As sunlight of all colors passes through air, the blue part causes charged particles to oscillate faster than does the red part. The faster the oscillation, the more scattered light is produced, so blue is scattered more strongly than red.
