The umbra in a shadow is the portion where light from a source is completely blocked. This is in the middle of the shadow.
The area around this, where light from part, but not all of the source shines is called the penumbra.
In the shadow cast by the moon in an eclipse, the penumbra is the partial shadow that occurs before the total eclipse, and the umbra is the 'total eclipse' portion
What else can I help you with?
Is this true or false total solar eclipse can be seen only by people in the area of Earth within the Moons umbra?
True. The umbra is the central darker total shadow of the Moon. Outside of this area, called the penumbra, is the lighter partial shadow. In this area, you would see a partial or annular eclipse. The umbra and penumbra are cone-shaped areas of full and partial shadow. The solar eclipse of January 14, 2010 (last week, as I write this) the Moon was so far away from the Earth that the umbra didn't reach all the way to the Earth. So the Sun was visible all the way around the Sun; and "annular", or ring-shaped eclipse.
Is Apollo 11 true or false?
It is true.
Is it true or false the troposphere is divided into the ionosphere and the exosphere?
That is false.
Is it true or false the sun is one of the largest stars in the galaxy?
True or False? Rewrite the statement The Sun is the largest star.
Is it true that If you want a space to look farther away you should color that space darker with a lot of detail?
false
Is it true that the umbra is the inner part of the shadow?
Not precisely. The umbra is the TOTAL part of the shadow. In a total eclipse, where the eclipsing object is spherical, then the "inner" part of the shadow is the umbra, but in a partial eclipse, there IS NO umbra; just the "penumbra", the partial shadow.
A total shadow is called an umbra True Or False?
True.
What is the darkest part of a shadow called?
The darkest part of a shadows is called the "umbra", which is actually Latin for "shadow". This is where the light source is completely blocked by the occluding body. The person viewing the umbra experiences a total eclipse.

The inner core contains genetic material true or false?
False. The inner core of the Earth is composed of solid iron and nickel, while genetic material is found in the nucleus of cells.
Is it true or false that shadow means you fill in the text in tones of gray?
False By:Unaxy
True or false the inner section of a bone has hard tissue called tarrow?
true
Each time the moon revolves behind the Earth it will pass through the Earth's shadow. True False?
False. Usually the Moon passes north or south of Earth's shadow.
True or false during a total solar eclipse the sky grows dark?
True, if you are in the shadow path of the eclipse.
when There is no requirement to take action to identify and discipline those responsible for the unauthorized disclosure of Controlled Unclassified Information?
False
What is the result of True AND False OR True?
True AND False OR True evaluates to True. IT seems like it does not matter which is evaluated first as: (True AND False) OR True = False OR True = True True AND (False OR True) = True AND True = True But, it does matter as with False AND False OR True: (False AND False) OR True = False OR True = True False AND (False OR True) = False AND True = False and True OR False AND False: (True OR False) AND False = True AND False = False True OR (False AND False) = True OR False = True Evaluated left to right gives a different answer if the operators are reversed (as can be seen above), so AND and OR need an order of evaluation. AND can be replaced by multiply, OR by add, and BODMAS says multiply is evaluated before add; thus AND should be evaluated before OR - the C programming language follows this convention. This makes the original question: True AND False OR True = (True AND False) OR True = False OR True = True
Is the inner core of the earth is solid and made primarily of iron is true or false?
True. The inner core of the Earth is solid and is primarily made of iron and nickel. The immense pressure from the layers above keeps the inner core in a solid state, despite its extremely high temperature.
