UV Light Penetration Depth

  1. May 11, 2015 #1
    For a photopolymer, the heuristic goes that longer wavelengths of UV light penetrate deeper than shorter wavelengths of UV light. For example, the UVA spectrum penetrates more deeply into the photopolymer than the UVC spectrum. What is the best way for this to be explained?

    Beer's law combined with a larger absorbance at short wavelengths, compared with longer wavelengths.
