Question

State difference between a luminous and a non- luminous body.

Answer 1

Hint: To know the difference we have to know what is luminous and what non luminous objects are. We know that luminous objects can emit light energy from their own body. They are visible by their own lights. Similarly, non-luminous objects cannot emit light energies so that they cannot be visible by their own. They are visible by the emitted light energy by the luminous bodies. Now from this definition we can write the differences between these two objects.

Complete answer:
We know that luminous bodies emit light energy by themselves, and non-luminous bodies do not emit light energies from their bodies. luminous objects can emit light energy so they are seen on their own but non luminous objects do not emit light energy on their own, so they are seen due to luminous bodies not by their own .

From these characteristics we can say, sun, candles or any electrical bulbs are the luminous objects and moon, chair, plants, human beings these are non-luminous objects. Luminous objects can cause the sensation of light. We know that luminous flames produce less heat.And the funny part is non luminous flames are light blue in color.

Note:We can get confused between luminous objects and luminous flames. Also similarly, we can say we can get confused between non luminous objects and non luminous flames. So, to solve these kinds of questions we have to gain detailed knowledge about these objects and flames.
