Brilio.net - An eclipse is a natural phenomenon that occurs when one celestial body blocks the light that goes to another celestial body. In the process of an eclipse, shadows play an important role. There are two types of shadows that cause an eclipse, namely umbra and penumbra. Understanding the shadows that cause an eclipse is important for understanding events such as solar eclipses and lunar eclipses. This article will discuss the two types of shadows in detail.
1. Umbra : Dark shadow that causes a total eclipse.The umbra is the darkest core shadow and is one of the types of shadow that causes an eclipse. This shadow is formed when a smaller celestial body is completely covered by the shadow of a larger object. In the case of a solar eclipse, the umbra is formed when the moon is directly between the sun and the earth, causing a small area of the earth to be in full shadow, thus creating a total solar eclipse.
A total solar eclipse is an example of how the umbra plays a vital role as a shadow that causes an eclipse. In the area under the umbra, sunlight will be completely blocked, making the sky dark for a few minutes. This phenomenon can only be seen in a small area of the earth that is directly in the path of the umbra. Likewise, in a total lunar eclipse, the earth's umbra covers the entire surface of the moon, causing the moon to appear red or completely dark.
Umbra as one of the shadows that causes eclipse is very interesting to observe. Total eclipse, both solar and lunar eclipse, occurs when an object completely enters the umbra shadow, producing a stunning effect in the sky. Many people try to witness this rare event because of its extraordinary beauty.
2. Penumbra: Partial shadow that causes a partial eclipse.The penumbra is a lighter shadow and is another part of the various types of shadows that cause eclipses. In this shadow, only part of the light is blocked by the celestial body in the center. When an eclipse occurs, the area under the penumbra will experience a partial eclipse, where only part of the light source is covered.
In a partial solar eclipse, the penumbra causes only a small portion of the sun to be covered by the moon. In the area under the penumbra, the sky will not be completely dark, but there will be a noticeable reduction in light. The penumbra is also the shadow that causes a partial lunar eclipse, where only part of the moon is covered by the earth's shadow.
One of the unique features of the penumbra as a shadow that causes an eclipse is that this phenomenon is more common and can be seen over a wider area than a total eclipse. In many cases, most people on earth can witness a partial eclipse when the penumbra passes over their area. Although not as beautiful as a total eclipse, a partial eclipse is still an interesting event to observe.
How do the umbra and penumbra work in an eclipse?The process of an eclipse involves two types of shadows that cause an eclipse, namely the umbra and the penumbra. When a solar eclipse occurs, the moon blocks sunlight that should reach the earth. The area under the umbra will experience a total solar eclipse, while the area under the penumbra will experience a partial solar eclipse.
Likewise in a lunar eclipse, the earth that is between the sun and the moon will emit two kinds of shadows that cause this eclipse. When the moon enters the umbra, a total lunar eclipse occurs, and when the moon is in the penumbra, a partial lunar eclipse is visible.
It is important to remember that the umbra and penumbra are key to understanding how eclipses are formed. Total solar and total lunar eclipses would not occur without the umbra shadow, which completely blocks out the light source.
The two types of shadows that cause eclipses, namely umbra and penumbra, play an important role in creating the phenomena of solar and lunar eclipses. Umbra is a full shadow that causes a total eclipse, while penumbra is a partial shadow that causes a partial eclipse. By understanding these two types of shadows, the phenomenon of eclipses can be seen as an extraordinary natural event, full of beauty and wonder.
