CHAPTER 7 ATOMIC STRUCTURE AND PERIODICITY
Questions
19. The equations relating the terms are νλ = c, E = hν, and E = hc/λ. From the equations, wavelength and frequency are inversely related, photon energy and frequency are directly related, and photon energy and wavelength are inversely related. The unit of 1 Joule (J) = 1 kg m2/s2. This is why you must change mass units to kg when using the deBroglie equation. Frequency is the number of waves (cycles) of electromagnetic radiation per second that pass a given point in space. Speed refers to the distance a wave travels per unit time. All electromagnetic radiation (EMR) travels at the same speed (c, the speed of light = 2.998 × 108 m/s). However, each wavelength of EMR has its own unique frequency, The photoelectric effect refers to the phenomenon in which electrons are emitted from the surface of a metal when light strikes it. The light must have a certain minimum frequency (energy) in order to remove electrons from the surface of a …(To be continued )
