Vision is perhaps the most useful of the senses for humans. More than 50% of the sensory receptors in the human body are located in the eyes, and a significant portion of the cerebral cortex is devoted to interpreting visual information. The eyes are responsible for detecting visible light, which ranges from 400 to 700 nanometers in wavelength. Objects can absorb and reflect different wavelengths of light. An object appears white if it reflects all wavelengths of light, and it appears black if it absorbs all wavelengths of light.
