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
Ultraviolet–visible spectroscopy non-bonding electrons (n-electrons) can absorb energy in the form of ultraviolet or visible light to excite these electrons to higher anti-bonding molecular orbitals. The more easily excited the electrons (i.e. lower energy gap between the HOMO and the LUMO), the longer the wavelength of light it can absorb. There are four possible types of transitions (π–π*, n–π*, σ–σ*, and n–σ*), and they can be ordered as follows: σ–σ* > n–σ* > π–π* > n–π*. UV/Vis spectroscopy is routinely used in analytical chemistry for the quantitative determination of different analytes, such as transition metal ions, highly conjugated organic compounds, and biological
