INTRODUCTION : • Who invented the computer? • What is computer? • How did the computer evolve? • Where did it start? Charles Babbage‚ a British professor mathematics is the man who invented the first computer in 1837. It was basically an mechanical type of calculator that also had a memory. The computer was powered by steam engine and used punched cards for programming. A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical

silver will be explored. Infrared radiation is invisible radiant energy‚ it lies between the visible light and the microwave portion of the electromagnetic spectrum. Heat is the main source of infrared energy‚ heat is produced by the movement of atoms and molecules. This experiment was conducted to investigate how black‚ white‚ and silver cans would absorb heat. The electromagnetic spectrum is made up of gamma rays‚ X-rays‚ ultraviolet‚ visible‚ infrared‚ microwaves and radio waves. What separates

radiating electric field (or electromagnetic signal) produced when radio stations broadcast? Include a description of what is producing the signal as well as the reasoning behind how this could produce a signal. We know that electromagnetic radiation is produced by accelerating charges. In the radio transmitter‚ electrons oscillate up and down and are thus accelerating. An electron will exert a force on another electron when they are some distance away‚ like charges repel. When the electron in

MATHEMATICAL MODELLING OF MICROWAVE HEATING OF FOOD By M . SHIVA KUMAR ( 04AG1008 ) Under the guidance of PROF. SURESH PRASAD ABSTRACT • The use of microwaves in the food industry is attributed to the lower time needed to increase the temperature of foodstuffs compared to the traditional heating methods. •However‚ the heating is not uniform and the products show hot and cold spots. • In order to analyze the behaviour of foods heated by microwave oven‚ a mathematical method was developed
