We call it 'wingardiem leviosa'
A luminous object can reflect light off other light sources. But it can also produce its own light.
No. Any object that is hot enough will produce light, regardless of what heated it.
Heat can not produce light without heating a certain object or material meaning heat by itself cannot produce light on its own.
An object through which light cannot pass is known as opaque.
Reflection
A luminous object is an object that can reflect light! examples of these objects are the moon, etc. hope that helped :)
a luminous object
You would call such an object opaque.
It is called transparent object I think
When the light combine with the speed in a photoelectric effect it produces a picture of the object.
moon
The non-luminous is those objects which do not produce its own light.It provide the light which is reflecting from another e.g.moon did not produce its own light,sun is giving the light to moon,moon reflecting the light of sun.
