i have no idea do you he he shame whoever wanted this
Luminous means the objects which emit light and i think there is no word iluminous in dictionary.instead that non luminous means which do not emt light by themselves
One is luminous and the other is illuminated. If you know what these words mean, that should be enough.
An illuminated object reflects light that came from somewhere else. A luminous object emitts its own light.
The candela measures luminous intensity, whereas the lumen measures luminous flux. In simple terms, you can think of luminous intensity as being similar to 'brightness', while luminous flux is similar to the rate at which light leaves its source.
-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.
A luminous body 'glows' on it's own (a firefly) while an illuminated body is seen with light. (a flash light at night on a book).
A star generates energy, including light, which it emits into space, i.e. it is luminous. A planet can only be seen because it reflects the Sun's light, i.e. it is non-luminous.
i don't know ask yourself
a star is a luminous pointed figure that shows up at night. A diamond rating is facts and information, cut, clarity, color, and more things on an diamond.
A planetary body is a non-luminous object rounded by it's own gravity that orbits a star or a stellar remnant. A moon, or satellite, orbits a planetary body.
The screw is to change between a luminous flame(orange) and non-luminous flame(blue). You should always screw the lock so that it covers the hole first.
Luminous objects give off light whereas illuminated objects relfect light, and thus appear to produce light. For example: A lightbulb is luminous because it gives off light whereas the moon is illuminated because it reflects the light of the sun.A luminous object shines with its own light; it produces its own light, like the sun. An illuminated object is lit by some outside source, like a light bulb or something lit up because your car's headlights fall on it at night, such as your garage door.
