Related Questions: Why FeCl3 has greater covalent character than FeCl2? Wave nature of elactromagnetic radiation? 17 terms. Scientists accept the evidence that supports this dual nature of light (even though it intuitively doesn't make sense to us!) 2-1-4 Quantum Properties of Electromagnetic Radiation Maxwell’s formulation of electromagnetic radiation leads to a mathematically smooth wave motion of fields. [1] It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays. The wave while travelling in another path is reflected from a surface at 1 9 km away and further travels 1 2 km to reach the same receiver. A single gamma ray photon, for example, might carry ~100,000 times the energy of a single photon of visible light. Thus, EMR is sometimes referred to as the far field. The wavelength of the wave associated with any material particle was calculated as: In case of photon, if it is assumed to have a wave character, its energy is given by E = hν where ν is the frequency of the wave and h is Pla… Besides, photons assume an essential role in the electromagnetic propagation of energy. Louis de Broglie, a French physicist, in 1924, suggested that all microscopic as well as macroscopic objects possesses dual character. Planck's constant is a physical constant named after Max Planck. The oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. Contrarily, wave nature is prominent when seen in the field of propagation of light. Not wave nature of electrmagantic radiation. EMR of visible or lower frequencies (i.e., visible light, infrared, microwaves, and radio waves) is called non-ionizing radiation, because its photons do not individually have enough energy to ionize atoms or molecules or break chemical bonds. In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. We can identify two properties of the radiation - wavelength ($$\text{200}$$ $$\text{nm}$$) speed ($$c$$). is done on EduRev Study Group by Class 11 Students. DPP-01 Wave Nature of Matter. EM waves are used for communication purposes, voice communication in mobile phones, telecommunication used in radio. 1 Thank You. In quantum mechanics, an alternate way of viewing EMR is that it consists of photons, uncharged elementary particles with zero rest mass which are the quanta of the electromagnetic force, responsible for all electromagnetic interactions. For the Love of Physics - Walter Lewin - May 16, 2011 - Duration: 1:01:26. An electromagnetic wave, propagates in a direction that is oriented at right angle to the vibration of both electric and magnetic field vectors ,transporting energy from the radiation source to an undetermined final destination. This relationship is given by Planck's equation E = hν, where E is the energy per photon, ν is the frequency of the photon, and h is Planck's constant.
