Suppose that the dot/area representing the longest wavelength of
color in this situation was located 21 mm from the baseline, and the dot/area
representing the shortest wavelength of color was located 36 mm from the
baseline (see Figure 9.4 on page 288 for help). If the solvent traveled 57 mm
from the baseline, what was the Rf for each of these two components of the
sample?
Rf value short wavelength = (distance moved by shortest/distance moved by solvent).
Rf value for long wavelength = (distance moved by longest/distance moved by solvent)
