INFRARED (IR) :- This  light is electromagnetic radiations with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometer (nm) to 1 mm. Wavelengths of these ra ys corresponds to a frequency range of approximately 430 THZ down to 300 GHz, and includes most of the thermal radiation emitted by objects near room temperature. Infrared light is emitted or absorbed by molecules when they change their rational-vibrations movements. It was first discovered in 1800 by astronomer William Herschel. Slightly more than half of the energy from the Sun arrives on Earth in the form of infrared radiation. The balance between absorbed and emitted infrared radiation has a critical effect on Earth's climate. History of Infrared:- The discovery of this radiation is ascribed to William Herschel, the astronomer, in th...

WIRELESS COMMUNICATION Introduction:- Wireless communication  is the communication between two or more points that are not connected by an electrical conductor. It permits services, such as long-range communications, that are impossible or impractical to implement with the use of wires The common wireless technologies use electromagnetic wireless telecommunications, such as radio. With radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including  cellular telephones ,personal digital assistants (PDAs), and wireless networking . Other examples include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and...

Rule of   "72 "      If you divide the  number 72 by the rate of interest, you get to know the  number of years it will take for you to double the money 72:   is sort of a magic number of personal finance, a.k.a known   as the rule of 72 in  personal finance parlance. All you   need to do is a quick calculation (mentally if you know   fifth grade math tables) and you can verify, if the cheeky   agent is giving you hogwash.     *Years:* If   you divide the number 72 by the rate of interest, you get to  know the number of years it will take for you to double the  > money. For instance, if the rate of interest is 9%, simply   divide the number 72 by 9% and the answer is eight. This is   the number of years it will take to double your money if you   invest it at 9% rate of interest.     *Interest:**...
