Umbra
The word “umbra” comes from the Latin word for “shadow”. Umbra refers to the innermost region of the shadow that appears to be the darkest. In other words, an umbra represents the part of the shadow where the light gets entirely obstructed by the blocking body.
Penumbra
The word penumbra originated from the Latin word “paene” which means “almost or nearly”. The penumbra is a portion of the shadow of an object where only a certain part of the beam of light gets obstructed by the occluding body. An observer located in the penumbra region sees only a partial eclipse.
Antumbra
The word “antumbra” originated from Latin word “ante” which means “before”. The antumbra refers to the portion of the shadow from which the obstructing object appears to be placed completely within the central region of the light source. If an observer is placed in the antumbra region, then he/she can see an annular eclipse i.e.
