X-rays and gamma rays are forms of electromagnetic radiation that do not differ in nature or properties; the designation of x or gamma reflects the way in which they are produced.

Thus, analysis of X-ray images of the body is a valuable medical diagnostic tool. Black Body Radiation. These episodes develop this picture.

In particular, we start from the assertion that light is a transverse wave. The wave nature of electromagnetic radiation refers to the way electromagnetic radiation travels outward from its source. But with the development of quantum theory, people like Einstein and Planck, showed that you also need to treat electromagnetic radiation as a particle or a photon. Wave nature of electromagnetic radiation failed to explain many phenomena such as black body radiation and photoelectric effect. The same is true in the neighboring region, the visible region (0.7–0.4 m) where electronic energy levels start to play a key role.

Recall that Maxwell's equations don't involve the Planck's constant, and thus can not describe the particle nature of the photon. electromagnetic radiation from space that does not reach Earth’s surface are some wavelengths of infrared radiation from distant objects, X-rays, and gamma rays. Dual Behavior of Electromagnetic Radiation: Orginally Electromagnetic Radiation was supposed to be having wave nature only and we could explain phenonmenon like interference and diffraction with the help the wave nature.

In addition to acting like waves, electromagnetic radiation acts like a stream of small "packets" of energy called photons. The passage of X-rays through materials, including biological tissue, can be recorded.

A complete Maxwell's equations should involve this missing element. Solids on heating emit radiations over a wide range of wavelengths. Electromagnetic radiation. While investigating the scattering of X-rays, he observed that such rays lose some of their energy in the scattering process and emerge with slightly decreased frequency. 11.2 Wave-like nature of EM radiation (ESADI) If you watch a colony of ants walking up the wall, they look like a thin continuous black line. In fact light as a wave is well described by Maxwell. But as you look closer, you see that the line is made up of thousands of separated black ants. DUAL NATURE OF ELECTROMAGNETIC RADIATION.

Electromagnetic radiation - Electromagnetic radiation - Compton effect: Convincing evidence of the particle nature of electromagnetic radiation was found in 1922 by the American physicist Arthur Holly Compton. X-rays are produced extranuclearly, which means that they are generated in an electric device that accelerates electrons to high energy and then stops them abruptly in a target, made usually of tungsten or gold.

Much of our present understanding of the electronic structure of atoms has come from analysis of the light emitted or absorbed by substances. Students will have a simple idea of electromagnetic radiation – that there are several types of radiation, similar to light, all of which travel at the same speed in empty space. Radiations emitted shift from lower frequency to a higher frequency as the temperature increases. But as I say, until the 1920s, people thought that that was the way you treated electromagnetic radiation. The photon model is not critically consistent with Maxwell equations, since it has a dual nature. As a wave, it is represented by velocity, wavelength, and frequency.

In the next region, the ultraviolet (0.4 m to 300 Å), electronic energy levels play the main role in wave–matter interaction.

... nature of wave pr opagation in free space, i. where there are neither conduction currents nor electrical .

But Wave nature of Electromagnetic Radiation could not explain certain things like Black body radiation & photoelectric effect. The waves have certain characteristics, given as frequency, wavelength or energy. How can we know? Additional information: All objects emit infrared radiation. Electromagnetic radiation can either acts as a wave or a particle, a photon.

The Wave Nature of Light. This involves oscillations in the electromagnetic fields as the wave moves. X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10^-8 to 10^-12 metre. Right, so let's, we talked about the wave properties of electromagnetic radiation. The basics of electromagnetic radiation are given at the beginning of the paper.

Nature and Properties of Electromagnetic Waves c02.qxd 1/20/2006 12:57 PM Page 23. sensing. To explain this, we need to explore the idea of polarisation.

To avoid interfering with very faint Another way that electromagnetic radiation has been described is in terms of a stream of photons. Electromagnetic waves are produced by a vibrating electric charge and as such, they consist of both an electric and a magnetic component.
