Hint: In this question, we need to comment on the given statement that whether the statement “Luminous objects emit light on their own” is true or false by following the general definition of the luminous object.
Complete step by step answer:
The objects which emit light of their own are known as the luminous objects. These objects emit light by following the principle of energy conservation, i.e., energy can be converted from one form to another form but cannot be stored or destroyed under any circumstances. The luminous objects are visible to us as they emit their own light, whereas the non-luminous objects are visible to us due to luminous objects.
Light can only be reflected from the surfaces only when light falls on it. There are some exceptions, such that the Black body does not reflect any light falling on it as it absorbs all the light falling on it.
Some of the examples of the luminous objects are the sun, stars, candles etc. Moon is not a luminous object as it receives its glowing light from the sun.
Hence, the statement “Luminous objects emit light on their own” is TRUE.
Note:
It is interesting to note here that the luminous objects always have some sort of chemical reactions in it so as to emit their own light. Also the objects emit light by following the principle of energy conservation.
