Answer 1

the umbra and penumbra

Step-by-step explanation:

The two parts of a shadow are the umbra and penumbra.

A shadow is an expression formed when light from a source is cut blocked by an opaque body.

Most shadows are made up of two parts, umbra and penumbra.

• The umbra is the darkest, and the innermost part of a shadow.
• In the penumbra, only a portion of the light source is blocked. It is more of like a partial shadow.

The umbra is directly formed by light which impinges on an opaque body and it completely cut off.
