Question

edges of the shadow are not as dark as the rest of the shadow. light from the sun and other wide light sources casts shadows with two parts. • the umbra is the central, darker part of a shadow where light is totally blocked. if you stood within an object’s umbra, you would not see the light source at all. • the penumbra is the lighter part of a shadow where light is partially blocked. if you stood within an object’s penumbra, you would be able to see only part of the light source. differentiate examine the image. explain the difference between the umbra and penumbra. check your answer.

Explanation:

The umbra is the central, darker part of a shadow where light is totally blocked (so you can't see the light source there). The penumbra is the lighter part of a shadow where light is partially blocked (so you can see part of the light source there). Visually, the umbra is the inner, darker region of the shadow, and the penumbra is the outer, lighter region surrounding the umbra.

Answer:

The umbra is the central, darker part of a shadow with total light blockage (no light source visible from within), while the penumbra is the lighter, outer part with partial light blockage (part of the light source visible from within). Visually, the umbra is the inner dark region and the penumbra surrounds it as a lighter region.
