The scattering due to molecule-sized particles ( as in air ) is greater in the directions both toward and away from the source of light than it is in directions perpendicular to the incident path. Scattering is significant for light at all visible wavelengths , but is stronger at the shorter ( bluer ) end of the visible spectrum , meaning that the scattered light is bluer than its source : the Sun .
