Electromagnetic Radiation
... Electromagnetic radiation (EM) is described in terms of its wavelength, frequency, or energy. All electromagnetic energy travels at the speed of light, c, which is 2.998 × 108 m/s, so wavelength (λ) and frequency (ν) are inversely related: c = λν. Long waves have a low frequency and short waves have ...

... (a) Energy difference for a transition from D to B = 5.0 eV – 2.5 eV = 2.5 eV. Thus the energy left with the electron = 3.0 eV – 2.5 eV = 0.5 eV. (b) A transition to A requires 5.0 eV – 1.5 eV = 3.5 eV, which is more than the electron energy, so this transition is impossible. Question 15 This questi ...
