In electromagnetism, electromagnetic waves in vacuum travel at the speed of light c, according to Maxwell's Equations. The retarded time is the time when the field began to propagate from a point in a charge distribution to an observer. The term "retarded" is used in this context (and the literature) in the sense of propagation delays.

Famous quotes containing the words retarded and/or time:
“Scholastic learning and polemical divinity retarded the growth of all true knowledge.”
—David Hume (1711–1776)
“[My father] was a lazy man. It was the days of independent incomes, and if you had an independent income you didn’t work. You weren’t expected to. I strongly suspect that my father would not have been particularly good at working anyway. He left our house in Torquay every morning and went to his club. He returned, in a cab, for lunch, and in the afternoon went back to the club, played whist all afternoon, and returned to the house in time to dress for dinner.”
—Agatha Christie (1891–1976)
