| For other uses, see Invisible (disambiguation).An object in this state is said to be invisible (literally, "not visible").However, its effects can also be seen in the real world, particularly in physics and perceptional psychology.Since objects can be seen by light in the visible spectrum from a source reflecting off their surfaces and hitting the viewer's eye, the most natural form of invisibility (whether real or fictional) is an object which neither reflects nor absorbs light (that is, it allows light to pass through it).Thus an object can be classified as "invisible to" a person, animal, instrument, etc.Invisibility by environment
An object may be classified as "invisible" if it cannot be noticed by use of sight due to environmental factors other than the fact that it doesn't reflect light.An object that might normally be seeable may be classified as invisible if it is:
