[edit] Materials Penetrants are classified into sensitivity levels. Visible penetrants are typically red in color‚ and represent the lowest sensitivity. Fluorescent penetrants contain two or more dyes that fluoresce when excited by ultraviolet (UV-A) radiation (also known as black light). Since Fluorescent penetrant

California is in a drought and farmers believe our only option is to take water from under the ground. But‚ groundwater depletion is causing a lot of bad things to happen. It is making the layer of clay above collapse‚ when the clay collapses the dirt above gives way and sinks. This sinking causes sinkholes and is very dangerous. The sinking also damages pipes‚ buckles walls of irrigation canals‚ and cracks homes. Although the sinking is already a big enough threat the water in general could

The Hubble Space Telescope is a space telescope that was carried into orbit by a Space Shuttle in 1990 and remains in operation. A aperture telescope in low Earth orbit‚ Hubble’s four main instruments observe in the near ultraviolet‚ visible‚ and near infrared. The telescope is named after the astronomer Edwin Hubble. Hubble’s orbit outside the distortion of Earth’s atmosphere allows it to take extremely high-resolution images with almost no background light. Hubble’s Deep Field has recorded some

Some species‚ such as the hummingbird‚ are believed to be able to see ultraviolet light because the flowers from which they drink the nectar have patterns that are visible only under the ultraviolet light. To find out what colors birds are attracted to‚ we can look at the colors of flowers and fruits birds tend to consume. Humming birds‚ for example‚ like the color red. Other species
