Invisible Woman render other people or objects fully or partially invisible too, affecting up to 40,000 cubic feet (1,133 cubic meters) of volume. She achieves these feats by mentally bending all wavelengths of visible, infrared, and ultraviolet light to bend around herself or her target without causing any visible distortion effects. According to the "Women of Marvel: Celebrating Seven Decades Handbook", Sue's retinas don't function conventionally and instead of just registering objects using reflected light, the retinas in Sue's eyes also interpolate shapes based on reflected cosmic rays, which in the Marvel Universe are always present in the atmosphere, granted usually only
Umkehr effect Umkehr effect The Umkehr is the time variation of the ratio of the scattered intensity at two different wavelengths. The word means 'reversal' in German. The Umkehr effect is observed when measurements are made with ultraviolet spectrophotometer of the ratio of the zenith sky light intensities of two wavelengths in the solar ultraviolet when the sun is near the horizon. The shorter of two wavelengths (intensity "I") is strongly absorbed and other (intensity "I' ") is weakly absorbed. If the value of log("I"/"I' ") is plotted against the sun's zenith angle, it is observed that this log-intensity ratio decreases as
