The Sunshine State is located in the southwestern part of the U.S., near the Mexico border, and is known for its long and dry summers. As the name suggests, the state is a location that enjoys great sunshine throughout the year. In fact, it boasts the third longest amount of sunshine of any state in the country, and is home to more than half of all the states with measurable amounts of sunshine. Because of this, sunshine is a huge factor in the growth and prosperity of Texas, Florida, and most of the other sunshine belt states. Without sunshine, many of these southern states would be almost hopelessly backwards, if not for the amount of rain they receive.
As far as what makes the sun so special, it is primarily the ultraviolet (UV) rays. These rays are long-wavelength and cannot be seen by the naked eye. Though it may seem strange to think about the difference in sunlight at various wavelengths, it is actually the biggest factor between what we see and what is produced by the sun. Long wavelengths of ultraviolet light have much shorter wavelength counterparts and are much easier to convert to usable energy, than wavelengths shorter than the 0.8 micrometre range.
Long-waisted air molecules (which are positively charged) are negatively charged and move with slower speeds than the air molecules which are closer to the sun’s rays. Thus, near-solar radiation has shorter wavelengths. Longer wavelengths have faster speeds and are longer. When it gets hotter, all objects radiate heat, including light, and heat energy can be converted to electricity in the form of infrared radiation. The longer the wavelength, the longer the infrared radiation.
Longer wavelengths can be seen, but only when they are passing through an obstruction. The reason is because the sun’s rays are distorted by gravity and reflect off objects such as space dust, ice crystals, etc., before they reach the observer’s eyes. This means that objects located at different angles to the sun will have different amounts of long and short wavelength radiation reflected back to them. Thus, distant objects look red, while nearby objects look orange or yellow. Similarly, long and short wavelengths appear to come from differing distances from the sun, and all objects in the vicinity of the sun, regardless of their position, appear to be the same color.
Infrared radiation is the type of radiation given off by objects which are closer to the sun or nearer to it in orbit. There is a wide spectrum of infrared wavelengths, which come from different sources. Long wavelength infrared radiation comes from hotter objects and is therefore hotter on the Earth than on the Sun. It is the radiation most associated with living things. The infrared rays are also emitted from lightning storms and from stars and are thus visible to people on the ground.
Ultraviolet light is a shorter wavelength of infrared radiation. It is generally accepted that humans have only a limited capacity to handle blue light, and that anything beyond this range is dangerous to our health. There is some evidence that blue light can help to prevent wrinkles, as well as to delay and promote healing. But when it comes to sunlight, no amount of research can convince people that ultra-violet rays are good for us.
