Why it is possible to see non-luminous objects?
It's often possible to see non-luminous objects if you illuminate them with a source of light, such as a flashlight, a candle, or a drop of golden sunshine. No object absorbs all of the light that falls on it, so some light is always reflected from it, and some of that reflected light finds its way to your eye. Once any of the light falling on the object has reflected from it, it's very much as if the object were self-luminous.
Do all light sources produce heat?
No. That's one of the things that makes fireflies an object of interest in chemical research.
When the color of an object is the color of the light it?
The object reflects all the incident light.
What happens to get a black object?
When all light that hits an object is absorbed by it the object appears black. Similarly we see a wight object when all light that hits the object gets reflected off it!!!!!
What color is an object the absorbs light of all wavelengths?
black body is the object which absorbs the light of all wavelength...........
How do you we see non luminous objects?
We see object from the light they either produce or reflect. The Sun gives off light waves. An object absorbs all colors but what you see. The reflected light then travels to your eyes where it is interpreted.
Is a lava a luminous object?
Yes, typically lava glows red, orange, yellow, or white before it cools sufficiently to harden and become a black solid. So, while it is still hot enough to remain a viscous liquid, it gives off light, making it luminous.
How can you see an object that is not luminous and does not produce its own light?
Light can reflect off it - that is how we see all the planets in out solar system.It can bend light (Einstienisn lensing) if it is massive enough.You can see changes in light/energy from objects that go behind it (eclipsing)

How do we see non -luminous objects?
We can see non-luminous objects because the light reflect off the object and into our eyes that's why at night you can only see a faint out line of the objects around you
Are stars luminous or non luminous?
All things, except black holes, are luminous. That includes stars. You might think that some other things are not luminous but that's because you can't see the kinds of light that they emit.
Which object in space produces rather than reflects light?
All stars produce light rather than reflecting light.
Which object gives off its own light?
All objects warm enough to glow. It depends on what you count as 'light'. If you count all electromagnetic radiation, then all objects above absolute zero give off their own heat and light. Except, maybe, black holes. The answer for them is not so clear-cut.
What is meant by luminous?
Giving off light, as a light source. The sun, a light bulb, and a candle are all luminous. The moon is not because it does not give off its own light but reflects it from the sun; it is illuminated.
Why an opaque or non luminous appears to be certain color?
First, you must understand that all color is determined by red blue and yellow light in different combinations. Any color is caused by light being reflected off the object. A red object for example reflects red light, and absorbs blue and yellow.
Is the temperature of a luminous flame greater or less than that of a nonluminous flame?
a non-luminous flame- when the air hole of the Bunsen Burner is open"when the air hole is open, more oxygen can enter the burner; therefore, hotter flame will be produced."its color is transparent or blueBlue flames are the hottest flamesa luminous flame is produced when the air hole is closed.."if the air hole is closed, oxygen cannot enter the burner; therefore, least hotter because the combustion is not fully complete with least oxygenA luminous flame has an outer of orange color and an inner of blue.Luminous flames emits more light than non-luminous flames.three things to produce flame1.fuel2.oxygen3.friction or source of sparkLuminous objects emit light. The sun is luminous; the moon is non-luminous.
Do all light sources produce heat?
No. That's one of the things that makes fireflies an object of interest in chemical research.
