Cat and mouse shadows

The video tutorial explains how shadows are formed when an object blocks light, causing the shadow to take the shape of the object. It further explores how the length of a shadow can vary depending on the angle of the light source. For instance, a mouse's shadow can appear longer than a cat's when the light is at a low angle, while the cat's shadow is shorter due to a high light angle. This illustrates the relationship between light angles and shadow lengths.
