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.
Hurricanes like Katrina are the most powerful storms in nature. They begin when a group of storms comes together over warm waters in the ocean along the equator. All summer long, these areas absorb heat from the sun. By late summer, the higher water temperatures allow storms to strengthen and grow.
