Abstract— the project is enlightening us about the characteristics and properties of electromagnetic wave .It also include radar‚ how does it works‚ its components and application of EM Wave in radar. 1. Electromagnetic Waves Electromagnetic waves are composed of oscillating electric and magnetic fields at right angles to each other and both are perpendicular to the direction of propagation of the wave. Electromagnetic waves differ in wavelength. Fig1. Propagation

different ways to study stars‚ planets and moons in the universe; but the most useful would have to be radio astronomy. Despite this‚ there are some who do argue that optical astronomy is the more useful of the two. Radio waves are a form of electromagnetic radiation and are given and received by many devices we use today‚ such as the radio‚ mobile phone or TV‚ but they have also been detected in space. Radio waves have long wavelengths at a low frequency‚ carrying less energy. Radio

Introduction When light interacts with matter‚ the structures and properties of atoms and molecules are determined. This technique is spectroscopy where it absorbs‚ emits‚ or scatters electromagnetic radiation. Electromagnetic radiation has particle-like properties having photons and quantum and wave-like

18th‚ 2012 Identifying Metallic Components Introduction: Spectroscopy is the study of the electromagnetic radiation emitted or absorbed by the atoms and molecules. A photon in short is light. Atoms produce light by putting energy in‚ the electron then becomes excited and goes up an energy level‚ the electron then falls back down to its ground state‚ and out comes a photon (light). The electromagnetic spectrum contains color that we can and cannot see. The color blue has the highest energy with

Each of us lives on big earth family‚ the earth provides us wealthy resources and energy .Nowadays，with rapid development of human science and technology‚ people crazy grab the earth’s resources‚ especially after the second industrial revolution accelerated the lighting industry and undoubtedly exacerbate the greenhouse effect and exhausted the earth energy. people crazy mining coal to generate electricity‚ harmful gas and dust and coal combustion has aggravated the earth’s atmospheric pollution

The waves associated with light are called electromagnetic waves because they consist of changing electric and magnetic fields.
