    society is being inundated with information wirelessly, through emissions of electromagnetic waves (EMF). Any room you enter is being blanketed with ever increasing amounts of, in some cases, highly powerful electromagnetic waves. These waves carry everything from cell phone traffic to wireless internet signals, to even conventional AM/FM radio signals. Although humans and animals cannot perceive most of these electromagnetic frequencies, they can affect biological organisms in many ways that scientists

    Electromagnetism is mainly found in the form of radiation. It can come from the sun, or even a radio. It is contained in electric and magnetic fields, and much of it travels in waves. There are many different types of electromagnetic radiation held in the electromagnetic spectrum. Electromagnetism impacts our world through energy, waves and fields, radiation, and technology. Radiant and electronic energy both come from the sun and give off light. When light is absorbed, the photons (light

    or three dimensions, depending on the nature of the wave and medium. Waves can be classified as either mechanical or electromagnetic. Mechanical waves require a medium and can be either transverse or longitudinal. Electromagnetic waves do not require a medium and are all transverse. Figure 1.a. shows the image of a transverse wave, figure 1.b. shows the image of an electromagnetic wave. In special circumstances standing waves can be produced, this happens when a sound wave interferes with its

    Remote Sensing is the science of acquiring, processing and interpreting images that record the interaction between the electromagnetic energy and matter (Sabins, 1997). Remote sensing offers extensive applications in almost every area of science from monitoring forest fires to geologic mapping . Although many aspects of remote sensing are complex and difficult to understand the basic theory behind remote sensing is simple physics. There are four major stages of remote sensing. The first stage

    talk over the phone many types of radiation are given out like microwave radio waves etc. There are two main types of radiation, ionizing and non-ionizing. The ionizing radiation is the energy is carried out by several types of particle rays (electromagnetic radiation), which is given off by the radioactive material, X-ray machines, and nuclear reaction. These energy bump electrons out of the molecules with which they interact, therefore creating ions. The non- ionizing radiation, such as the release

    Heat is actually light, but it is a light that is invisible to us, or not in the visible portion of the Electromagnetic Spectrum. Infrared light is the heat that we refer to normally and is located just below the color red in the Electromagnetic Spectrum. Its name is literally its definition. “Infra,” which means “below,” then “red.” So, infrared, or “below red,” is below red on the Electromagnetic Spectrum. We can see things that do not give off their own light because of reflection. When a color reflects

    19th century prompted a revolution in atomic science and human communication. Predicted and then proven, radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than those of infrared light and a frequency between about 104 and 1011 or 1012 Hz. The initial discovery in conjunction with its placement in the electromagnetic spectrum indicated a turn of events in the future of scientific studies and electronics. Through rapid development and practical
