On what basis is the most accurate position of the core shadow determined on a round object?

Answer and explanation

Correct answer: Where the surface turns away from direct light

On a rounded form, the core shadow is located where the surface turns away from the direct light and the illuminated plane no longer receives it effectively. Its position depends on the light direction and the object’s curvature, not on the cast shadow or outline thickness. Therefore, option A is correct. The cast shadow falls onto another surface, while paper whiteness is only a material property.
