Illuminated objects
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.

Objects that produce or emit light are called luminous objects. These objects generate their own light through a process such as incandescence or bioluminescence. Examples include the sun, light bulbs, and fireflies.
objects are visible to us only when?
When hot objects emit visible light due to being heated, it is called incandescence. This phenomenon occurs as the atoms in the object vibrate at higher temperatures, causing them to release photons in the visible spectrum.
Non-luminous. Objects which produce light of their own or give out or emit their own light are called luminous objects. Objects which do not produce light of their own, on the other hand, are called non-luminous objects. Luminous objects are objects like stars, sun and other celestial bodies which give out their own light. Objects surrounding us are not such light emitting objects. Therefore, we are surrounded by non-luminous objects.
A microscope is an instrument that uses a combination of lenses to produce enlarged images of tiny objects. This allows for the detailed examination of small structures that are not visible to the naked eye.
Objects that don't give out light are called non-luminous objects. They do not produce their own light but can reflect light from other sources, making them visible. Examples include the moon, which reflects sunlight, and everyday items like furniture, rocks, or walls. These objects are typically perceived due to the illumination provided by nearby luminous sources.
