The phrase "cast a shadow" refers to the act of creating a darkened area or silhouette on a surface or in a particular space, typically due to the obstruction of light by an object. When an object blocks or intercepts the path of light, it prevents the illumination from reaching specific areas, resulting in the projection of a shadow.

This figurative usage suggests the creation of a cloud of doubt, suspicion, or negativity, tarnishing the reputation, success, or perception of something or someone.
In a literal sense, shadows are created when an object obstructs a light source, such as the sun, a lamp, or a candle. Varying factors, such as the shape, size, and opacity of the object, as well as the angle and intensity of the light source, determine the characteristics of the cast shadow. These elements influence factors such as the size, position, length, and sharpness of the shadow, enhancing the overall visual appearance of the scene.
Generally, shadows serve as visual cues allowing us to perceive the depth, shape, and movement of objects in our surroundings. They can evoke different emotional responses, depending on their context and content, as shadows often carry connotations of mystery, secrecy, or impending danger. The intricate play of light and shadow can also enhance the aesthetic appeal of artwork, architecture, and photography, adding depth, drama, and atmosphere to the composition.
