By the reflected light from those objects, which is the case for nearly everything. Just look around yourself at what you can see.
because there is no light reflecting off of the non-luminous object into your eyes to let you see it.
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.
as we know moon reflects the sun light and moon is a non luminous object we can see the reflection of the sun's light
How do you see a luminous object?
A TV, when it's on and showing an image is luminous. When it's off, it's non luminous.
Having a non-luminous body means that it is not a see-through body. Many insects have a non-luminous body. Non-luminous body also means an object that cannot reflect light.
It is a non luminous object because it does not give out it's own light !
no it is not
Because of stone of luminous has object
Non luminous materials do not emit light that we can see. Most elements that are not radioactive fall into this category. Non luminous bodies are those which do not produce their own light. For example: moon etc.
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
An non-luminous object can be any oject that doesn't produce light, e.g. wood, metal, plastics, etc.
