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 a little shadow that goes in and out with me,
And what can be the use of him is more than I can see.
He is very, very like me from the heels up to the head;
And I see him jump before me, when I jump into my bed.”
—Robert Louis Stevenson (1850–1894)
“The shadow of your sorrow hath destroyed
The shadow of your face.”
—William Shakespeare (1564–1616)
“Beneath the sun’s rays our shadow is our comrade;
When clouds obscure the sun our shadow flees.
So Fortune’s smiles the fickle crowd pursues,
But swift is gone whenever she veils her face.”
—Ovid (Publius Ovidius Naso)
