Question: (CNN) -- Three men were sentenced to prison for forcing an African-American man out of a South Carolina convenience store, threatening him with a chainsaw and stealing his car, an incident the Department of Justice said was fueled by hate.

Thomas Blue Sr., 49, owner of the convenience store, was sentenced Tuesday to 13 years in prison in the 2007 incident. A second man, Judson Hartley Talbert, was sentenced to nine years, the department said. Blue's son, Thomas Blue Jr., 29, was sentenced to three years.

The three pleaded guilty in December to conspiring to deprive and depriving Dahndra "Ervin" Moore of his right to engage in a federally protected activity -- entering the convenience store -- and also to conspiring to carjack and carjacking his car, authorities said. The elder Blue also pleaded guilty to depriving two other people, both white, of their right to engage in a federally protected activity and using a firearm in relation to a crime of violence against those two.

The defendants admitted that the elder Blue "forcibly escorted" Moore out of a Marlboro County, South Carolina, store known as the Stop and Shop after he entered to use the restroom, the statement said.

"Once outside, the elder Blue forced the victim to the ground and Blue Jr. threatened the victim with a chainsaw while a small crowd watched," according to the Department of Justice statement.

While the attack was occurring, Talbert stole Moore's car, authorities said. Later, the elder Blue used a pistol to threaten two white men who he thought were trying to help the victim, including one who showed up to retrieve Moore's car. 1. Who owned the store?

Question: Infrared radiation is used in industrial, scientific, and medical applications. Night-vision devices using active near-infrared illumination allow people or animals to be observed without the observer being detected. Infrared astronomy uses sensor-equipped telescopes to penetrate dusty regions of space, such as molecular clouds; detect objects such as planets, and to view highly red-shifted objects from the early days of the universe. Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus.

The onset of infrared is defined (according to different standards) at various values typically between 700 nm and 800 nm, but the boundary between visible and infrared light is not precisely defined. The human eye is markedly less sensitive to light above 700 nm wavelength, so longer wavelengths make insignificant contributions to scenes illuminated by common light sources. However, particularly intense near-IR light (e.g., from IR lasers, IR LED sources, or from bright daylight with the visible light removed by colored gels) can be detected up to approximately 780 nm, and will be perceived as red light. Sources providing wavelengths as long as 1050 nm can be seen as a dull red glow in intense sources, causing some difficulty in near-IR illumination of scenes in the dark (usually this practical problem is solved by indirect illumination). Leaves are particularly bright in the near IR, and if all visible light leaks from around an IR-filter are blocked, and the eye is given a moment to adjust to the extremely dim image coming through a visually opaque IR-passing photographic filter, it is possible to see the Wood effect that consists of IR-glowing foliage. 1.
