The ending of Joy of Life's shadow was not specified in the novel.
Shadows are created by objects blocking the transmission of light, making it impossible for light to pass through opaque objects and forming a darker area. Light travels in a straight line in the same uniform medium and cannot pass through an opaque object, thus forming a shadow. There were three conditions needed to produce a shadow: a light source, an opaque or translucent object, and a place where the shadow could be displayed. If any of these conditions were missing, there would not be a shadow. The length and direction of the shadow could be changed according to the change of the light source and the position of the object. Shadows were divided into umbra and penumbra. The umbra was the part that was completely covered, causing it to be completely dark, while the penumbra was the dark part around it. Therefore, the appearance of shadows was an optical phenomenon formed by light being blocked by objects.
