The Challenge

The 10th in our new challenge layout catering for all aspects of nature for us nature lovers.

As you can see the title will start with the category which will make it easier for me when choosing what challenge to do next, I can see the challenges I have already run in this category.

For this challenge please add your images of SHADOWS.

Interesting Facts

> A shadow is an area where direct light from a light source cannot reach due to obstruction by an object. It occupies all of the space behind an opaque object with light in front of it.

> The cross section of a shadow is a two-dimensional silhouette, or reverse projection of the object blocking the light.

> The sun causes many objects to have shadows and at certain times of the day, when the sun is at certain heights, the length of shadows change.

> Shadow length changes dramatically throughout the day. The length of a shadow cast on the ground is proportional to the cotangent of the sun’s elevation angle.

> For a non-point source of light, the shadow is divided into the umbra and penumbra. The wider the light source, the more blurred the shadow. If two penumbras overlap, the shadows appear to attract and merge. This is known as the Shadow Blister Effect.

If there are multiple light sources there are multiple shadows, with overlapping parts darker, or a combination of colors. For a person or object touching the surface, like a person standing on the ground, or a pole in the ground, these converge at the point of touch.

> The farther the distance from the object blocking the light to the surface of projection, the larger the silhouette (they are considered proportional). Also, if the object is moving, the shadow cast by the object will project an image with dimensions (length) expanding proportionally faster than the object’s own length of movement.
