Why do luminous object glow in the dark only?
Luminous objects emit light through a process called luminescence, where they convert energy into light. This light emission is what makes them glow in the dark. Non-luminous objects do not have this capability, so they do not glow in the dark.
Does an luminous object cast a shadow?
because there is no light for it to reflect off
How does reflection help us see non luminous objects?
Reflection occurs when light rays bounce off a surface and into our eyes. When light rays reflect off non-luminous objects, they reveal the object's color, texture, and shape by bouncing off the object's surface and into our eyes, allowing us to see the object even if it does not produce light of its own.
How can a flashlight be non-luminous?
infra red maybe??? get a remote and your camera phone and you'll see what i mean or A flshlight can be non-luminous because the batteries from the flashlight gives the energy that makes light.
Why does Rigel shine as bright as Betelgeuse even though Rigel is much smaller than Betelgeuse?
Rigel appears as bright as Betelgeuse because it is hotter and more luminous, even though it is smaller. The luminosity of a star depends on both its temperature and size, so a hotter, more luminous star can shine as brightly as a larger, cooler star.

Is an eye luminous?
No. Eyes are not luminous. They observe or perceive light but they do not emit light. Luminous means "emit light." There are various species of animals, such as deer, cats, and dogs, whose eyes have the ability to reflect light which sometimes make them appear to glow in the dark as they reflect a flashlight, headlight, or other light that is shining in their direction. But even then, the eyes do not produce their own light so they are not luminous.
Is a glow worm luminous?
Here is a very singular thing: the Glow-worm's eggs are luminous even when still contained in the mother's womb.
What are luminous and non luminous materials?
Luminous means "giving off light", or glows in the dark (since luminosity is detected by the eyes, it usually refers to the visible part of the electromagnetic spectrum). Many materials emit a wide range of radiation other than visible light, which is why some radioactive materials were used as glow in the dark paints, and why the Curies focused on a particular radioactive isotope (because it glowed in the dark). Some materials can even store energy from visible light and emit it later, which is why some of my luminous objects have to be "charged" by a light bulb or the sun. Some chemical combinations can emit light for a while, such as the stuff in lightning bugs, which we can replicate in production lines to make glow sticks. Non luminous materials do not emit light that we can see. Most elements that are not radioactive fall into this category.
What type of object pollute water?
Oil can pollute the water (you might not consider that an object) and when people throw trash in rivers or ocean or even lakes the water can be polluted.
Which is better for cooking luminous or non-lominous flame?
For cooking, a non-luminous flame is generally better than a luminous flame. A non-luminous flame produces higher temperatures and more efficient combustion, resulting in faster and more even cooking. Luminous flames, on the other hand, are typically cooler and can leave soot on cookware, which may affect the taste and appearance of the food.
How do planets shine even if they are not luminous bodies?
They don't. They reflect light from the sun.
Luminous orange posts near fields are what?
Luminous orange posts near fields mark the location of water. This makes it easy for farmers to find the irrigation valves even when plants are growing.
What are some sources for baryonic dark matter?
I presume you mean, "What might baryonic dark matter consist of?" It MIGHT be non-luminous gas, MACHOs (a cute acronym), condensed matter like black holes & white dwarfs, and brown dwarfs. The measured ratio of hydrogen to deuterium to helium in our Universe precludes the possibility that a large proportion of dark matter could be baryonic. The proportion could even be negligible.
Why did the sun turn black?
Our Sun has been highly luminous for billions of years. It would be very difficult to halt the energy-producing processes in the core and make it "turn black". Even after the fuel is exhausted, our Sun won't become a black hole because it lacks the mass - likely after a red giant stage it will eventually shrink to a white dwarf and remain luminous in that state for a very long time indeed before going dark.
