Answer:
Umbra .
Explanation:
A shadow formed by a point light source such as a flashlight is called an umbra. It is uniformly dark and has sharp, well-defined edges. A shadow formed by an extended light source such as a fluorescent light tube has a central dark umbra surrounded by a lighter penumbra region.
