Phases of the moon occur because we can see only that part of the moon which reflects light towards us.
The changing shape of the bright part of the Moon that we see is called its phase. The moon is illuminated because it reflects the light from the sun. The part of the moon facing the sun is lit up. The part facing away from the sun is in darkness.

New Moon is a phase of the moon cycle in which it is not visible at all.

On the next day, a small part of the moon is visible. Thereafter, the moon appears to be expanding day by day.
On a special day, the moon appears completely full and visible. This is known as Full Moon. 
This apparent growing of the moon is also called a Waxing of the moon.

Which moon is also referred to as "Dark Moon"?

  1. Full Moon

  2. Waning Crescent

  3. New Moon

  4. Waning Gibbous
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The moon is visible on earth because the light from the sun falls on it, gets reflected from it and enters the eyes of the people who are watching it on earth.  The moon appears crescent, half, full, not at all, etc, depending on its position with respect to the sun and the earth.

The light falling on any part of the moon gets reflected. However the light reflected only from some part of the moon reaches the earth. Only that part is visible to the people on the earth.
On the new moon day, the moon is on the same side of the earth as that of the sun with respect to earth. No light from the moon reaches the earth and it becomes invisible. Its apparent colour is black, i.e. same of that as that of the night sky.
Hence it is also called as dark moon.

For practical understanding, you can perform the experiment given below
Take a torch, switch it on and place it on a table.
Stand in front of the source of light of the torch.
Take a small ball and hold it at a height same as that of the torch and facing the torch.
You will notice that the ball appears dark.
Now if you change the position of the ball, keeping the height same, you will notice that only some part of the ball appears illuminated.
If you place it diametrically opposite to the torch, but at height slghtly higher than your head, the entire ball gets illuminated.

The phases of the moon are due to situations similar to this experiment.
