To avoid interfering with very faint 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. Recall that Maxwell's equations don't involve the Planck's constant, and thus can not describe the particle nature of the photon. 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. 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. 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. 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.
Additional information: All objects emit infrared radiation. The photon model is not critically consistent with Maxwell equations, since it has a dual nature. The wave nature of electromagnetic radiation refers to the way electromagnetic radiation travels outward from its source. How can we know? Thus, analysis of X-ray images of the body is a valuable medical diagnostic tool. Electromagnetic radiation can either acts as a wave or a particle, a photon.

But as you look closer, you see that the line is made up of thousands of separated black ants.

X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10^-8 to 10^-12 metre. The waves have certain characteristics, given as frequency, wavelength or energy. DUAL NATURE OF ELECTROMAGNETIC RADIATION. As a wave, it is represented by velocity, wavelength, and frequency. Radiations emitted shift from lower frequency to a higher frequency as the temperature increases. Black Body Radiation. In addition to acting like waves, electromagnetic radiation acts like a stream of small "packets" of energy called photons. Much of our present understanding of the electronic structure of atoms has come from analysis of the light emitted or absorbed by substances. The Wave Nature of Light. Solids on heating emit radiations over a wide range of wavelengths. In fact light as a wave is well described by Maxwell. 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. But as I say, until the 1920s, people thought that that was the way you treated electromagnetic radiation. But Wave nature of Electromagnetic Radiation could not explain certain things like Black body radiation & photoelectric effect. Another way that electromagnetic radiation has been described is in terms of a stream of photons. Right, so let's, we talked about the wave properties of electromagnetic radiation. In the next region, the ultraviolet (0.4 m to 300 Å), electronic energy levels play the main role in wave–matter interaction. Electromagnetic waves are produced by a vibrating electric charge and as such, they consist of both an electric and a magnetic component. The basics of electromagnetic radiation are given at the beginning of the paper. A complete Maxwell's equations should involve this missing element. 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.

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. Electromagnetic radiation. 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. The passage of X-rays through materials, including biological tissue, can be recorded. In particular, we start from the assertion that light is a transverse wave. To explain this, we need to explore the idea of polarisation. These episodes develop this picture. This involves oscillations in the electromagnetic fields as the wave moves. 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. Wave nature of electromagnetic radiation failed to explain many phenomena such as black body radiation and photoelectric effect. ... nature of wave pr opagation in free space, i. where there are neither conduction currents nor electrical .
