caption: The image shows a graph depicting the absorption and absorption of a wave, with the text "Absent Aggregation" written above it. The graph is composed of a series of curved lines, each representing a different wave, and the x-axis of the graph is labeled with the wavelength of the wave, while the y-axis is labeled as the frequency of the absorption. The colors used in the graph are blue, green, and red, respectively, which represent the different wavelengths of the waves.
