Chemistry Class 11 Chapter 3 - Classification of Elements and Periodicity in Properties. The electromagnetic spectrum of an object has a different meaning: it is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. Calculate the range of frequencies of visible light from 3800 to 7600 A°? A particular wave is characterized by three properties: wavelength, frequency, and speed. The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. Download books and chapters from book store. So, the radiations emitted may vary in intensity, but should have same colour. According to Bohr’s theory, the stationary states for electrons(n= 1, 2, 3,…) in the hydrogen atom are known as ____. Class 10 Class 12. Class 11 Chemistry Structure of Atom. These waves are called electromagneticwaves or electromagnetic radiations. According to which, light was supposed to possess a particle like character. Ans: The energy which is produced by the oscillating body and which is propagated in the form of waves through space is called electromagnetic radiation. When anelectrically charged particle moves under acceleration, alternating electricaland magnetic fields are produced and transmitted. The change in color shows, that wavelength also changes .This indicates non continuous flow of energy. Electromagnetic Wave Theory.
