Because they still absorb and scatter some light.
objects are visible to us only when?
Illuminated objects
Illuminated objects
The term used to describe objects that are visible or reflect light is "luminous."
Those objects would be too cold to emit significant amounts of visible light.
Visible objects in the sky include the Sun, Moon, stars, planets, satellites, meteors, and the International Space Station (ISS). Telescopes or binoculars can make some objects like planets and clusters of stars easier to see.
illuminatedThats the right answer for a plus.
The microscope makes transparent objects visible to enable study.
Objects that don't give out light are called "non-luminous objects." These objects reflect light that falls on them, making them visible to our eyes.
They reflect and scatter visible light that comes from an external source.
The term used to describe objects that are visible because of reflected light is "luminous." However, if you're referring specifically to objects that do not emit their own light but are visible due to reflecting light from another source, the term "illuminated" is more appropriate. These objects can be seen only when light from a source, like the sun or a lamp, bounces off them.
