The image displays two diagrams illustrating the formation of shadows from different light sources. Diagram 'b' shows a large, extended light source casting both a dark central shadow (umbra) and a lighter outer shadow (penumbra) onto a surface, with labels indicating "large light source," "source," "object," and "penumbra region." Diagram 'a' depicts a small, point-like light source casting only a dark central shadow (umbra) onto a surface, with labels indicating "small light source," "object," and "shadow (umbra)." The overall context appears to be an educational illustration of light and shadow principles, likely related to astronomy or physics. The image is a scan of a printed page and does not depict any location or scene within a city.
