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:

    I have often told you that I am that little fish who swims about under a shark and, I believe, lives indelicately on its offal. Anyway, that is the way I am. Life moves over me in a vast black shadow and I swallow whatever it drops with relish, having learned in a very hard school that one cannot be both a parasite and enjoy self-nourishment without moving in worlds too fantastic for even my disordered imagination to people with meaning.
    Zelda Fitzgerald (1900–1948)

    He [Pompey] stands, the shadow of a great name.
    Marcus Annaeus Lucan (39–65)

    I verily believe
    My fair impression may
    Be all from that one day
    No shadow crossed but ours....
    Robert Frost (1874–1963)
