The intense absorption of light isdue to the frequency of the absorbed light beingequal to one of the free periods of the… … in which the ordinates represent the refractive in-dex, and the abscissae the frequency of the vibra-tion ; the refracting substance is supposed to havea free period whose frequency is represented byat. It will be noticed that there is a gap in thecurve just after passing this frequency; thus…
