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
Photovoltaic effect electric energy. The photovoltaic effect can also occur when two photons are absorbed simultaneously in a process called two-photon photovoltaic effect... The photovoltaic effect was first observed by French physicist A. E. Becquerel in 1839. He explained his discovery in "Comptes rendus de l'Académie des sciences", "the production of an electric current when two plates of platinum or gold immersed in an acid, neutral, or alkaline solution are exposed in an uneven way to solar radiation." Besides the direct excitation of free electrons, a photovoltaic effect can also arise simply due to the heating caused by absorption of the light.
