ABSTRACT

Microwave has been discovered to be a highly significant appliance over the years, and it is now utilized in a variety of applications including telecommunications, radar detectors, wood curing and drying, and medical treatment of specific disorders.
However, certain characteristics make them perfect for cooking, which is by far the most popular application of microwave energy. Microwaves can pass through plastic, glass, and paper, but they are reflected by metal surfaces, and foods (particularly liquids) absorb them. A meal cooked in a traditional oven is heated from the outside in as it gently absorbs the hot air from the oven. Microwaves, on the other hand, heat food more faster since they permeate all layers of the food at the same time. Microwaves agitate molecules inside a piece of food or a container filled with liquid, heating the item.
The Microwave Oven must be assembled in order to achieve a specific aim and for each component to communicate with one another. This article explains each of the steps/processes involved in putting this project together.

CHAPTER ONE
INTRODUCTION
Microwaves are a part of the electromagnetic wave spectrum, which includes all kinds of energy that travel across space and are created by the interplay of electric and magnetic fields. The different wavelengths (or frequencies) and emission, transmission, and absorption behaviors of various types of waves are used to divide the spectrum into subgroups. Electric and radio waves, microwaves, infrared (heat) radiation, visible light, ultraviolet radiation, X-rays, gamma rays, and electromagnetic cosmic rays are all part of the spectrum. Microwaves have frequencies ranging from.11 to 1.2 inches (0.3 and 30 centimeters)
In a 1932 study published in the first edition of Alta Frequenza, Nello Carrara appears to have coined the word “microwaves.”
Microonde is an Italian term. During World War II, the word came to be used to denote wavelengths of less than 30 cm. These waves were far shorter than those used in communications at the time, yet they were utilised in RADAR.
1 GHz corresponds to a wavelength of 30 centimeters (to convert from frequency to wavelength, just divide the speed of light 300,000,000 meters per second by the frequency in cycles per second to get meters of wavelength).
