What are the phases of the Moon? Explain with the help of diagram.

Solution

Moon does not produce light of it's own. It reflects light of the sun falling on it. On new moon day, moon is between the Sun and the Earth and no reflected light from it reaches the earth. We cannot see moon on that day. The visibility of moon increases every day till fifteenth day from the new moon day, the full phase of the moon is visible.



So, the waxing and waning of moon periodically, as it revolves around the earth is called phases of moon.
