Luminous intensity is measured in Candelas.
If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, its total luminous flux emitted into that angle is one lumen. Alternatively, an isotropic one-candela light source emits a total luminous flux of exactly 4π lumens. The lumen can be thought of casually as a measure of the total "amount" of visible light in some defined beam or angle, or emitted from some source. A standard North American 100 watt incandescent light bulb emits 1500-1700 lumens,[1] while a standard European 230 V model emits 1200-1400 lm.[2] A 100 watt high-pressure sodium vapor lamp emits around 15,000 lumens.[3] The number of lumens produced per watt of power consumed is the wall-plug luminous efficacy of the source.

What energy do all objects give off?
All objects give off thermal radiation.
What are luminescent objects?
A luminous object is something that emits/gives off light - eg sun, star, light bulb, A non-luminous object is something that doesnt have/give off its own light - eg moon, diamond, wood. Non-luminous objects can only be seen because they reflect light, which is given off by luminous objects.
How does an object give of light?
If an object gives off light, it is a luminous object.The luminous object gives off its energy and we see it. If you shine light on an object, it is an illuminated object, it just reflects the light back into your eyes.
What is luminouse and non-luminouse?
i think luminous means when something gives off light and non-luminous means when something does not give off light.
What do all objects give off?
All objects give off thermal radiation.
What are the luminous objects?
Sun stars fire fireworks that sort of stuff
Are candles and campfire luminous objects?
Yes because they emit or give off light
What energy do all objects give off?
All objects give off thermal radiation.
How can a non luminous body be made luminous Give an example?
Luminous objects create light .A non luminous object does not give off light.For instance, my feet are not luminous.Our sun and the rest of the stars in the universe are luminousNon-luminous objects are the ones who doesn't have its own light like you can say moon,trees, branches,plants, metals mirrors bricks etc.

When a lamp is turned off is it luminous or non-luminous?
If the bulb is switched off, then we would call it non-luminous.
What is luminous materials?
Luminous materials are materials that give off light.
How do we see 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

What is the difference between illuminated objects and non-luminous objects?
Luminous - bodies are objects which exhibit their own light.EXAMPLE:-SUNnon-luminous bodies are objects that reflect light from luminous bodiesEXAMPLE:-moonLuminous bodies are insects that give a light, such as the glow worm. Non luminous bodies do not glow o their own. it can also refer to things in space; such as planets, moons and stars
What is luminouse and non-luminouse?
i think luminous means when something gives off light and non-luminous means when something does not give off light.
Does luminous light give off heat?
yes
