Shadows were dark areas formed by objects blocking the transmission of light and unable to pass through opaque objects. Light rays travel in a straight line in the same uniform medium. The darker area formed by the inability to pass through the opaque object is what we often call a shadow. The necessary conditions to produce a shadow were light and an opaque object. When light passes through an object, the object will produce a shadow on the path of the light. This is what we usually call a shadow. The size and shape of the shadow depended on the shape and size of the object and the position of the light source. When the light source was further away from the object, the angle of the light was smaller, so the shadow was longer. When the light source was closer, the angle of the light was larger, and the shadow became shorter. The formation of shadows was also closely related to the straight line transmission of light. The especially dark part in the middle of the shadow was called the umbra, and the dark parts around it were called the penumbra. The formation of a shadow required three conditions: light, shelter, and screen.
