Prism

In optics, a prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application. The traditional geometrical shape is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type. Some types of optical prism are not in fact in the shape of geometric prisms. Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, plastic and fluorite.

A dispersive prism can be used to break light up into its constituent spectral colors (the colors of the rainbow). Furthermore, prisms can be used to reflect light, or to split light into components with different polarizations.

How prisms work

Light changes speed as it moves from one medium to another (for example, from air into the glass of the prism). This speed change causes the light to be refracted and to enter the new medium at a different angle (Huygens principle). The degree of bending of the light's path depends on the angle that the incident beam of light makes with the surface, and on the ratio between the refractive indices of the two media (Snell's law). The refractive index of many materials (such as glass) varies with the wavelength or color of the light used, a phenomenon known as dispersion. This causes light of different colors to be refracted differently and to leave the prism at different angles, creating an effect similar to a rainbow. This can be used to separate a beam of white light into its constituent spectrum of colors. Prisms will generally disperse light over a much larger frequency bandwidth than diffraction gratings, making them useful for broad-spectrum spectroscopy. Furthermore, prisms do not suffer from complications arising from overlapping spectral orders, which all gratings have.

List of Humanx Commonwealth planets

This is a list of the fictional planets in the Humanx Commonwealth series of novels by Alan Dean Foster.

Alaspin

Alaspin has large jungles surrounded by equally large savannas and river plains; its only notable celestial feature is two moons.

Currently the planet has no sentient race; the native race died out, possibly by racial suicide, over 75,000 years ago leaving behind hundreds of ancient, abandoned cities that have proved a source of fascination to modern xeno-archaeologists.

A variety of lifeforms currently live on Alaspin, most notably the Alaspinian minidrag.

Annubis

Annubis is most notable for the fictional Hyperion forests from which the fictional drug bloodhype is manufactured. In an attempt to eradicate the highly addictive and deadly drug, the trees were burned in 545 A.A. and are thought to be completely destroyed.

The planet first appeared in the novel Bloodhype.

Blasusarr

Blasusarr is the homeworld of the AAnn race and is often called the Imperial Home World. Climate is dry and hot, largely desert, the preferred atmospheric conditions of the AAnn. Beyond this, little is known about Blasusarr other than the fact that it is very well-protected by a detection and space defense network. Its capital city, also the capital of the AAnn Empire, is Krrassin.

Jeff Scott Soto

Jeff Scott Soto (born November 4, 1965) is an American rock singer of Puerto Rican descent. He is most well known for being the lead singer for the group Talisman from 1990 till the end of Talisman in 2007, the vocalist on Yngwie Malmsteen's first two albums, and the lead vocalist for Journey on their 2006–2007 tours after Steve Augeri had to leave the band because of an acute throat infection. His style ranges from Hard Rock to Heavy & Power Metal, but he is also influenced by classic soul music singers such as Sam Cooke as well as Journey vocalist Steve Perry, and Freddie Mercury from Queen.

Career

Soto came to prominence in the early 1980s via his involvement with several Yngwie Malmsteen records. The bands Soto has been involved in included Panther, Axel Rudi Pell, Eyes, Talisman, Takara, Humanimal, Human Clay, Kryst The Conqueror, Redlist, The Boogie Knights and Soul Sirkus.

Soto has sung background vocals on several albums by artists such as Lita Ford, Steelheart, Fergie Frederiksen, Glass Tiger, House Of Lords, Stryper, Saigon Kick, and many others.

Anza

Anza may refer to:

Anza (river)

The Anza is a 35-kilometre (22 mi) Alpine torrent of the Ossola in northern Italy. It flows from the glaciers of Monte Rosa through the Valle Anzasca and into the river Toce, of which it is a right tributary.

Its own principal tributaries are the Pedriola, the Tambach, the Orlovono and the Quarazza near Macugnaga and the Olecchia at Bannio Anzino.

Anza, California

Anza is a census-designated place located in southern Riverside County, California, in the Anza Valley, a semi-arid region at a mean elevation of 3,921 feet (1,195 m) above sea level. It is located 13 miles (21 km) south of Idyllwild, and approximately 35 miles (56 km) southwest of Palm Springs, 143 miles (230 km) southeast of Los Angeles, California and approximately 75 miles (121 km) northeast of San Diego, California, being traversed by State Route 371. The population was 3,014 at the 2010 census.

Locally, Anza and several other mountain communities (including Garner Valley, Idyllwild, Pinyon Pines and Aguanga) are collectively referred to as "the Hill."

The ZIP code is 92539, and the community is inside area code 951.

Geography

According to the United States Census Bureau, the CDP covers an area of 27.7 square miles (71.7 km²), 99.70% of it land and 0.30% of it water.

Regional geographic subdivisions of the unincorporated town include Anza Valley and Cave Rocks (Central); Tripp Flats, Chandler Heights and Cahuilla (West) as well as Oak Spring, Burnt Spring and Heller Spring (East). The Anza Valley in which the unincorporated town is nestled is bordered by three significant mountains- Cahuilla Mountain to the West, Thomas Mountain to the northeast and Beauty Mountain to the southwest.
