A sunbeam, in meteorological optics, is a beam of sunlight that appears to radiate from the position of the Sun. Shining through openings in clouds or between other objects such as mountains and buildings, these beams of particle-scattered sunlight are essentially parallel shafts separated by darker shadowed volumes.
Examples of volumetric lighting are seeing sunbeams shining through a window and seeing sunbeams radiating when the Sun is below the horizon, also known as crepuscular rays. The term seems to have been introduced from cinematography and is now widely applied to 3D modeling and rendering , especially in the development of 3D video games .
Crepuscular rays are noticeable when the contrast between light and dark is most obvious. Crepuscular comes from the Latin word crepusculum, meaning "twilight". [2] Crepuscular rays usually appear orange because the path through the atmosphere at dawn and dusk passes through up to 40 times as much air as rays from a high Sun at noon.
Sunbeam Products is an American company founded in 1897 that has produced electric home appliances under the Sunbeam name since 1910. Its products have included the Mixmaster mixer , the Sunbeam CG waffle iron , Coffeemaster (1938–1964) [ 2 ] and the fully automatic T20 toaster .
Therefore, the sunbeam hitting the ground at a 30° angle spreads the same amount of light over twice as much area (if we imagine the Sun shining from the south at noon, the north–south width doubles; the east–west width does not). Consequently, the amount of light falling on each square mile is only half as much.
"I'll Be a Sunbeam" (also called "Jesus Wants Me for a Sunbeam") is a popular children's Christian hymn composed by Nellie Talbot; it is sung to music composed in 1900 by Edwin O. Excell. Due to its age, the hymn has entered the public domain in the United States .
On a Sunbeam is a science fiction webcomic, [2] later released as a graphic novel, [1] by American cartoonist Tillie Walden.Set in a spacefaring science fiction world, the plot follows the development of the protagonist Mia, who joins the crew of the maintenance ship Aktis and attempts to reconnect with a lost love.
"Jesus Wants Me for a Sunbeam" is a song originally recorded by the Scottish alternative band the Vaselines for their EP Dying for It. [1] It is a parody on the Christian children's hymn "I'll Be a Sunbeam", which has the opening line "Jesus wants me for a sunbeam."
