प्रश्न
Suppose the moon emits light of its own. Would it still have phases? Justify your answer.
उत्तर
No, it will not have the phases because the phases are due to the reflection of different intensities of light falling on moon from the sun due to its revolution around the Earth. Now, since the moon will have its own light, it need not to be dependent on Sun’s light to glow, so it will glow continuously and completely.
