i don't know

When three sources are used, how many sources must be blocked by the object to produce the umbra? the dark penumbra? and the light penumbra?

so i would put a part where some light falls.

The umbra is part of the shadow that is entirely dark. i don't know the definitions of dark penumbra or light penumbra.

yes i have tried to figure it out but i can't figure it out at all
