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! :)
If the bulb is switched off, then we would call it non-luminous.
Luminous objects are things that let out light without the help of anything else. Examples are:The SunGlow wormsLight bulbsGlow sticksStarsLighted candlesSparksFlamesHeating coilsLEDsTV ScreensDischarge tube
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
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.
A flashlight can be luminous when turned on, emitting light from the bulb. It can be nonluminous when turned off because at that point it is not emitting any light.
Yes, light bulbs themselves are considered nonluminous because they do not produce light on their own. They require electricity to pass through a filament, which then emits light, making the bulb appear luminous.
i think luminous means when something gives off light and non-luminous means when something does not give off light.
No, a flashlight is considered luminous because it generates its own light by converting battery power into light energy. Nonluminous objects do not produce their own light and rely on external light sources for illumination.
A nonluminous body is an object that does not emit light of its own. Instead, it reflects light from other sources, such as the Sun or artificial light sources. Examples of nonluminous bodies include the Moon, planets, and most asteroids.
Yes, a mirror is nonluminous. It does not emit light by itself, it only reflects light emitted by other things.
because it has light
Luminous sources of light are objects that emit light due to their own energy, like the sun or a light bulb. Non-luminous sources of light are objects that reflect light from luminous sources without emitting light themselves, like the moon or a mirror.
A light bulb is a luminous object because it produces its own light through the process of converting electrical energy into light energy. An illuminated object is one that reflects light from another source.
Luminous objects emit their own light, such as the sun or a light bulb, whereas non-luminous objects do not produce light but reflect light from other sources, like the moon or a table. Luminous objects are sources of light, while non-luminous objects only appear visible when light is shone upon them.
An ordinary frosted incandescent bulb is a luminous source because it produces light through its own incandescent filament. It does not rely on external light sources to produce light.
The yellow color in a luminous flame is basically the black-body emission from hot particles of soot in the flame. they are hot, and they glow like the filament of a light bulb. In a blue flame, there are no particles of soot to give that incandescent radiation. Instead, the main color you see is blue emission from the high-energy C2 molecule.
