Shadow cast by a large light source. Illustration showing the shadow cast by a boy's hand in front of a flashlight, a spread-out source of light. No light from the flashlight reaches the centre area in shadow, or umbra, but some light reaches the areas around the umbra, creating an area of partial shadow, or penumbra. | |
