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 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)

    When a shadow flits across the landscape of the soul where is the substance?
    Henry David Thoreau (1817–1862)

    Hemingway is great in that alone of living writers he has saturated his work with the memory of physical pleasure, with sunshine and salt water, with food, wine and making love and the remorse which is the shadow of that sun.
    Cyril Connolly (1903–1974)
