Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. List and explain three things that can happen to a light wave when it enters a new medium. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. All wavelengths are collectively referred to as electromagnetic wavelengths and not merely the narrow range of wavelengths and frequencies identified as visible light. • Explain dual behaviour of electromagnetic radiation - 13261241 1. The particle model explains this behavior because particles have well-defined positions. 1 Nevertheless, the dual models of wave and particle behavior provide a useful description for electromagnetic radiation. One the one hand, it could explain the photoelectric effect satisfactorily but on the other hand, this was not consistent with the known wave behavior of light which could account for the phenomena of interference and diffraction. The exact nature of electromagnetic radiation remains unclear, as it has since the development of quantum mechanics in the first quarter of the 20 th century. 1. Electric and magnetic fields obey the properties of superposition.Thus, a field due to any particular particle or time-varying electric or magnetic field contributes to the fields present in the same space due to other causes.

You may need to download version 2.0 now from the Chrome Web Store. 3.6.2. Since the speed of electromagnetic radiation in a vacuum is always the same, radiation may be characterized by specifying either λ or v. The other quantity can always be calculated from Equation \ (\ref {1}\). Dual nature of EM waves - law EM radiation is so-named because it has electric and magnetic fields that simultaneously oscillate in planes mutually perpendicular to each other and to the direction of propagation through space. Explain the dual behaviour of electromagnetic radiation .
