Fluorescent or incandescent.
The scientific term for an object that does not let light through is "opaque." Opaque objects do not allow light to pass through them and therefore block the transmission of light.
Planets that emit their own light are referred to as "self-luminous" or "intrinsically luminous" objects. However, in astronomy, most planets do not produce their own light; instead, they reflect the light of their parent stars. The term "exoplanets" often describes planets outside our solar system, and while they may have some heat or light from internal processes, they primarily shine by reflecting starlight. In contrast, stars are the celestial bodies that generate their own light through nuclear fusion.

Accommodation is the eye's adjustment to light.
The generic term for cells that consume harmful bacteria and foreign objects is phagocyte.
Luminous objects.
The term used to describe objects that are visible or reflect light is "luminous."
Luminous objects are those that emit their own light, such as stars, the sun, and certain artificial light sources like lamps and LEDs. In contrast, non-luminous objects do not produce light but can reflect it, such as the moon or a painted wall. The term "luminous" comes from the Latin word "luminosus," meaning "full of light."
illuminatedThats the right answer for a plus.
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.
The non-luminous is those objects which do not produce its own light.It provide the light which is reflecting from another e.g.moon did not produce its own light,sun is giving the light to moon,moon reflecting the light of sun.
Reflection of light is the phenomenon where light rays bounce off a surface after striking it. A mirror and a smooth metal surface are two examples of objects that can reflect light.
Opaque is the term used to describe an object or substance that stops all light passing.
Gravitational lensing.
translucent
The term that refers to how far apart two objects or places are located is distance. Distance can be measured in various units such as meters, kilometers, miles, or light-years.
I believe, the term breakup would mean refracting white light to show the different shade of purple to red light. The object of speaking is called prism.
