Some lasers emit radiation in the form of light. Others emit radiation that is invisible to the eye, such as ultraviolet or infrared radiation. In general, laser radiation is not in itself harmful, and behaves much like ordinary light in its interaction with the body.
Hurricane Katrina is arguably the most notorious storm of the 21st century. The storm made landfall as a Category 5 near Miami before striking Louisiana as a Category 3 storm. Katrina was the third deadliest, and costliest hurricane in US history with more than 1,200 deaths and $108 billion in damage.
Hurricane Sandy â unofficially known as Superstorm Sandy â was making landfall, affecting millions of people along the U.S. Mid-Atlantic and Northeast coasts. It was to be the deadliest and most destructive hurricane of the 2012 Atlantic hurricane season, as well as the second-costliest hurricane in United States history.
