In order to see, the eye must receive light; and darkness is the absence of light. Most of the objects we see around us are visible by reflected light -- reflected sunlight or reflected artificial light. Since darkness is the absence of light, there is no light in the darkness to be reflected from chairs, tables, or people to our eyes, and therefore we can not see these objects.
You see objects because visible light( a small portion of the electromagnetic spectrum) is reflected off the surface of something into your eye. All different colors have a different wavelength which defines their frequency. When you see a red object, that object is absorbing all the colors except for red which is then reflected into your eye.
it is because of diffused reflection,Diffuse reflection is the reflection of light from a surface such that an incident ray is reflected at many angles rather than at just one angle as in the case of specular reflection.
Because we were made that way nobody actually knows why.
That part of the visible spectrum that is reflected from its surface.
illuminatedThats the right answer for a plus.
Because certain objects can absorb specific wavelengths of light(color) and they reflect the waves that they cannot absorb. the reflected wave of light is the visible color of the object.

we see things when a light source goes into our eyes or when it reflects off an object
It is used to observe features of stars, planets, and other celestial objects by their visible light (generated or reflected).

that color is absorbed by the object (therefore you don't see that color. Only reflected colors can be seen)
Different materials absorb different wavelengths of visible radiation from sources like the sun or light bulbs. The wavelengths that are not absorbed are reflected as visible radiation, and the color we see depends on the wavelength of that reflected light, with a longer wavelength correlating to more reddish colors, and shorter wavelengths with more bluish colors. White objects reflect all of the visible radiation that strike them, which is why they absorb less heat than black objects, which reflect much less visible radiation.

Because they still absorb and scatter some light.
objects are visible to us only when?
