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:

    Whether changes in the sibling relationship during adolescence create long-term rifts that spill over into adulthood depends upon the ability of brothers and sisters to constantly redefine their connection. Siblings either learn to accept one another as independent individuals with their own sets of values and behaviors or cling to the shadow of the brother and sister they once knew.
    Jane Mersky Leder (20th century)

    The whole shadow of Man is only as big as his hat.
    Elizabeth Bishop (1911–1979)

    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)
