Study Notes

Shadows are formed when an opaque object blocks light, creating a dark patch on the opposite side of the light source.
The three things required for shadow formation are a source of light, an opaque object, and a surface where the shadow will form.
Shadows are always black in color and do not display the actual color or details of the object, only showing the outline.
The size and clarity of a shadow depend on the size of the object, source of light, distance between the object and the light source, and distance between the object and the surface.
The length and position of shadows change throughout the day as the sun moves across the sky, with shadows being longest in the morning and late afternoon, and shortest at noon when the sun is directly overhead.
