As you can see in the above figure of the electromagnetic spectrum that as the wavelength of a radiation increases its frequency decreases. Although as its wavelength decreases, its energy increases. There are many more useful educational material which the students can download in pdf wave nature as well as particle nature. Maxwell’s equation of electromagnetism and Hertz experiments on the generation and detection of electromagnetic waves in 1887 strongly established the wave nature of light. Earned Point(s): 0 of 0, (0) It represents the height of the wave. Other characteristics of a wave are amplitude and period. The nature of the relationship between the frequency (the number of oscillations per unit time) and wavelength (the length of each oscillation) of light becomes apparent when studying the broad range of the electromagnetic radiation spectrum. These rays are produced in a discharge tube at a pressure below 0.01 rom of mercury. (ii) Cathode rays are deflected by electric field and magnetic field. Unit 18: Atoms And Nuclei Maxwell suggested that when an electrically charged particle moves under acceleration that time alternating electrical and magnetic fields are produced which helps the particle in propagation. 11.3 Photoelectric Effect. An electromagnetic wave has dual (wave–particle) nature. They are the basis for everything in the Universe. It is represented by. The nature of the experiment determines whether a wave or a particle description is best suited for understanding the experimental result. Different regions of the electromagnetic spectrum are identified by various names. Properties of Cathode Rays (i) Cathode rays are not electromagnetic rays. This is called speed of light. Electromagnetic radiation is a flow of energy in which electrical and magnetic fields vary simultaneously. 18 b. – In terms of kinetic energy K, de Broglie wavelength is given by The theory of electromagnetic radiation was given by Scottish scientist Sir James Clerk Maxwell in the early 1870s. Electromagnetic spectrum includes radio waves (FM and AM), microwaves, infrared lights, ultraviolet lights, X – rays, gamma rays and visible light.
