Moon is a non-luminous body. It has no light of its own. It only reflects the light of the sun falling on its surface. When this reflected light reaches the earth, we see the moon. Only that part of the moon is visible, which reflects the sunlight towards the earth. On the New Moon Day, the moon is present between the sun and the earth. Thus, the reflected light from ‘the moon does not reach the earth, and hence, is not visible.

The night just after the new moon day, we see the crescent moon. It happens because only the reflected light from the crescent part reaches the earth. The rest of the moon is only faintly visible because the sunlight reflected from the earth also falls on the moon’s disc.

The crescent goes on increasing every day, till, on the fifteenth day, the full bright face of the moon is visible. On this day the earth is between the sun and the moon, such that the night side of the earth is facing the day side of the moon. This is called full moon day. This gradual increase in the bright disc of the moon is called waxing of the moon.

After the full moon, the bright face of the moon goes on decreasing every night. This decrease in the bright disc of the moon is called waning of the moon. By another fifteen days, the new moon is formed. This waxing and waning of the disc of the moon, are the moon revolves around the earth is called phases of the moon.
