Answer:
The applications of physics have played a key role in the development of technology. Today we see the applications of physics in every walk of life. Some of the major technologies based on the applications of physics are as follows : 1. Electromagnetic waves are used in radio, television, radar and wireless communication. 2. Newton?s concept of gravitation is used in geostationary satellites which help us in forecasting weather and in geophysical survey. 3. X-rays are used in radiotherapy, in detecting fractures or dislocations in bones, in studying crystal systems, in engineering and industry. 4. The study of thermodynamics has helped to design heat engines which have revolutionized the industry. 5. The study of electricity has led to the development of electric appliances like electric motors and generators which are the backbones of industry. 6. Nuclear power stations based on nuclear fission constitute one of the major sources of energy. 7. The concepts of modern electronics find extensive use in telephone exchanges, robots, etc. 8. The discovery of silicon chips has brought a revolution in computer industry. 9. Geothermal energy, i.e., the heat in the depth of the earth is being used these days. The tidal energy in the oceans and solar energy too can be converted into other forms of energy and used. 10. Radioactive isotopes are now being widely used in medicine, agriculture and industry. These technologies have made our lives comfortable and materially prosperous.
