At first light it DOES sound a bit confusing.
First, the definition of the term 'NON-LUMINOUS'; 'Not capable of PRODUCING light but can be capable of REFLECTING light from another source'.
For instance, our MOON is NON-LUMINOUS as it REFLECTS light from the Sun. The SUN is LUMINOUS as it produces light that is REFLECTED off the surface of the moon. And so, LUMINOUS means capable of PRODUCING light.
Now closely examine your flashlight.
The BATTERIES produce electrical energy which is transferred to the BULB which emits light, thus LUMINOUS. The tiny little BULB emits quite a lot of light for its small size. However, the bulb is contained within a concave silvered cone which REFLECTS,(NON-LUMINOUS) gathers and channels the emitted light from the BULB (LUMINOUS) into a BEAM which ILLUMINATES whatever you are pointing the flashlight at.
Our cameras would be just paperweights if there were no NON-LUMINOUS surfaces for the light to REFLECT off of, back into the camera lens, onto the 'plate' thus etching the image. For example, take a photograph in the dark without the flash and what do you get. No LUMINOUS, no NON-LUMINOUS.
And so there we have LUMINOUS and NON-LUMINOUS, ILLUMINATING our lives. Enjoy! :)
GLOW WORM is a luminous object,because it emits its own light.
The word "luminous" means giving off light. Naturally, fluorecent lights (when turned on) are luminous, that is their purpose.
it is definitely NOT luminous because of the way it is made. and take it from me i am a scientist
non luminous
If the bulb is switched off, then we would call it non-luminous.
Bodies which emit light are luminous bodies and those who don't emit light are known as non luminous bodies Example - stars are luminous bodies while planets are non luminous bodies Tube light is a luminous body while a chair is non luminous
sun (a luminous object) emits its own light and the moon ( a non luminous object ) reflects the light from the sun to earth that's how we can see the moon. The same way gold is a non luminous object.
Because of stone of luminous has object
Planets( Mercury, Venus, Earth, Jupiter, Saturn, Uranus, Neptune) and also Moons are Non-Luminous objects they don't emit light. The reason we see them because they reflect light from the Sun.
because it has light
Only if it is lit.
The earth is Non-luminous.
It's non-luminous
A TV, when it's on and showing an image is luminous. When it's off, it's non luminous.
what is luminous, non luminous and illuminous source of light.
It is luminous
luminous
A luminous flame flickers while a non-luminous flame remains steady.
-A non-luminous flame is when the air hole of the Bunsen burner is closed but a luminous flame is produced when the air hole is opened.-A luminous flame has an outer of orange colour and an inner of blue. A non-luminous flame has an outer of blue and an inner of orange.-A luminous flame produces soot while a non-luminous does not produce soot.-A luminous flame is weak and unsteady. A non-luminous flame is strong and steady.-A non-luminous flame is very hot while a luminous flame is not too hot.
If the bulb is switched off, then we would call it non-luminous.
the types of non-luminous are bulb,candles ect
