Step-by-step explanation:
According to this supposition, the computation of atomic refraction depends on the average value of the refraction of the CH2 group and those of certain atoms. If, however, the individual atomic refractions show even small deviations, this method cannot be used.
Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. This refraction is due to the velocity of light through air, decreasing with increased density.
