Answer:
If you look at the picture of the baby and the umbrella, you will notice that both of them leave a very dark shadow. The umbrella is there to help you remember that the dark part of the shadow is called the umbra. See how umbra and umbrella sound alike? Also, many umbrellas are black, so that similarity in words can help you remember that the umbra is black. Some shadows have lighter areas, too, and those are called penumbras.
See the answer Below Mate:-
Define of Umbra :-
=>The umbra (Latin for "shadow") is the innermost and darkest part of a shadow, where the light source is completely blocked by the occluding body. An observer in the umbra experiences a total eclipse.
Define of penumbra:-
=>A penumbral lunar eclipse occurs when the Sun, Earth, and the Moon are imperfectly aligned. When this happens, the Earth blocks some of the Sun's light from directly reaching the Moon's surface and covers all or part of the Moon with the outer part of its shadow, also known as the penumbra
For your Kind Info:-
=> There is one more known as Antumbra.
Define of antumbra:-
=>The antumbra (from Latin ante, "before") is the region from which the occluding body appears entirely within the disc of the light source. An observer in this region experiences an annular eclipse, in which a bright ring is visible around the eclipsing body.
