Shadow

Shadow

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 lengths of shadows change.

Famous quotes containing the word shadow:

    The shadow of your sorrow hath destroyed
    The shadow of your face.
    William Shakespeare (1564–1616)

    The shadow of the Venetian blind on the painted wall,
    Shadows of the snake-plant and cacti, the plaster animals,
    Focus the tragic melancholy of the bright stare
    Into nowhere, a hole like the black holes in space.
    John Ashbery (b. 1927)

    The best history is but like the art of Rembrandt; it casts a vivid light on certain selected causes, on those which were best and greatest; it leaves all the rest in shadow and unseen.
    Walter Bagehot (1826–1877)
