| Dec 9 at 15:16 | comment | added | CGCampbell | I would ask it slightly different... would it be possible for an 'object' to be completely transparent to our visible spectrum, and reflective to UV or IR or even higher/lower? | |

| Dec 9 at 7:22 | comment | converted from answer | Professor Sushing | We do bump into things that do not reflect or emit visible light. Why do you think people carry torches in the dark? | |

| Dec 8 at 18:20 | comment | added | Dan Getz | The wavelength describes what a photon looks like, but not what an object looks like; viewing an object is more complicated than a single number. | |
| Dec 8 at 15:05 | comment | added | Aaargh Zombies | Just to be clear, it this question predicated on the existence of physical objects with sufficient density for the to interact with humans (EG, a solid, not a gas), which exist outside of the visible human spectrum? For example, that there are invisible rocks, tress or life forms of some variety? | |
| Dec 8 at 14:32 | comment | added | MisterMiyagi | What exactly are you asking? Are you asking how humans avoid transparent objects, say glass? Are you asking why there aren’t many bump'able objects outside the visible range? Are you asking why most objects aren’t transparent even though we only see a limited spectrum? | |

| Dec 7 at 21:43 | comment | added | Filip Milovanović | A related interesting thing is that objects that we can see can have features that are invisible to us, but are revealed by cameras/sensors that can record frequencies outside of the visible range (like ultraviolet (UV) or infrared (IR), and beyond). Some examples are layering in some sedimentary rocks that otherwise look uniform (no visible layers), coloration of some flowers that look plain to us but appear vibrant/multicolored to insects, heat "glowing" from the human body in infrared, different surface layers of the Sun revealed by observing it in various frequencies, etc. | |
