What Are The Phases Of The Moon?
The moon consummates its cycle about the Earth about in 30 days and it almost completes 13 cycles around the Earth in a year. This duration of a complete cycle around the Earth is also called as a lunar month. If we see the moon at the night, at the start of and at the end of a lunar month, we can easily analyze that there is a change in the shape.
This is because when the location of the moon in accordance with the sun is changed, the interaction of them and the sun causes the various visual appearances of the moon. In this article, we will discuss the different phases of the moon and their names. It will be very beneficial for you to increase general knowledge, so read the article till the end.
When the Earth totally comes between the sun and the moon, or the difference is of very few degrees, a very little area of the moon is lightened that it is almost invisible. This phase is called new moon and this occurs on the starting of a lunar month.
This second quarter phase rises around the midnight or at the noon. The crescent occurs when there is a 90-degree angle between the moon and the sun. A very small area of the moon is lightened so we can see a D shape or crescent.
The Full Moon
This 3rd quarter part of the phases is also called the full moon and this transpires when the moon is stationed at an angle of 180 degrees to the sun or they are in opposite position to each other. The entire front face is illuminated by the sun, of the moon and we can see the full round shape of the moon. It appears at the noon and the light can be seen through the night.
The Waning Moon
This last phase of the moon occurs when again the moon is at the angle of 90 degrees with the sun. But this time the diverse side is illuminated so we see the shape C instead of D, of the moon. This phase rises at the mid of the night and we can see it reaching its highest position at the dawn.
The Complete Cycle
In the picture above, we can see the complete phases. The important thing we should notice that the entire moon is not lightened by the sun. We can take the example of a ball if that if we throw the light using a torch on the ball, the area which is in front of the light is ablaze and the area behind is dark.
