Electromagnetic Energy
？？ 1. White light seems to be acombination of all colors. The energy that comes from a source of light is notlimited to the kind of energy you can see. Heat is given off by a flame or anelectric light. On a cloudy day it is possible to get a sunburn even though youfeel cool. Visible light and the kinds of energy that produce warmth andsunburn are examples of electromagnetic energy.
？？ 2. The sun is 93 millionmiles from the&39;earth. Yet we can use energy from the sun because electro-magnetic energy travels through space.
？？ 3. Many other kinds ofenergy are also types of electromagnetic energy. Radio, television, and ra- darsignals travel from transmitters to receivers as low-energy electromagneticwaves. Infrared (红外线的) radiation is an electromagnetic wave. When it is absorbed by matter,heat is produced. Waves of infrared and visible light have more energy thanwaves of radio, television, or radar. Ultraviolet rays（红外线） ahd X-rays areelectromagnetic waves with even greater amounts of energy. Infrared radia- tionis used in cooking fo？？od？？ and heating buildings. Sunlight and electric lights arepart of our require- ments for normal living. Ultraviolet radiation is usefulin killing certain disease organisms. X-rays and gamma rays have so much energythat they travel right through solid objects. They can be used to de- tect andtreat cancer. X-rays are used in industry to find hidden cracks in metal, andin medicine to re-veal broken bones.
？？ 4. Usually we useelectricity to generate electromagnetic energy. The source of most of our energyis the sum Heat from the sun causes water to evaporate. When the water falls tothe earth as rain, some of it is trapped behind dams and then used to operateelectric generators. Other generators are powered？？ by coal, but the energystored in coal came from the sun, too.
？？ 5. Until recently, thesource of the tremendous amount of energy given off by the sun was a puz- zle.If the sun depended on chemical reactions, it would have used up all its energylong ago. Experi- ments with electromagnetic radiation led to the theory thatmass can be converted into energy. About forty years after the theory wasproposed, nuclear energy was harnessed (利用) by man. Chemical en- ergy comes from electron (电子) rearrangement. Nuclear ene？？rgy comes from a change in the nucleus of anatom. Compared with chemical reactions, nuclear reactions release millions oftimes more energy per pound of fueL Wenow believe that the sun&39;s energy comes from the nuclear reactions in which hy-drogen is changed into helium (氦）.
？？ 6. Nuclear energy isbeginning to compete with coal as an economical source of power to generate, electricity.It is also being used to operate engines in large ships. Scientists continue toseek new and better methods of obtaining and using energy.？？
