Question
Why is the Moon non-luminous even if we see the light coming from it at night?
- It produces its own light
- It emits its own light
- It reflects sunlight falling on it
- None of the above
Hint:
Luminous objects are those which emit light on their own like stars, sun, etc.
The correct answer is: It reflects sunlight falling on it
- Luminous objects are those which emit light on their own like stars, sun, etc.
- Moon doesn’t give off light of its own, that’s why the moon is considered a non-luminous body. All its light we see is reflected from the sun and to a very minor effect, from the reflection of sunlight off the earth. In a total lunar eclipse where the moon is hidden behind the dark side of the earth, it becomes completely dark.
