- The emergence of line spectra from a gas when a current passes through it was an observed phenomenon waiting for an explanation in the early 20th century. The atomic line spectra coming from elements such as hydrogen had been analyzed since the late 19th century. By studying the wavelength of the emerging radiation of hydrogen, experimenters found (often by trial and error) that the wavelengths in those spectra were described by the formula 1 = R ( 1/2 - 1/2 ) where R is known as the Rydberg constant. It has a value of R=1.097 × 107 m-¹. The variables n₁ and no are integer numbers (n₁ = 1, 2, 3, 4, ...). As experiments continued, scientists began to see more and more characteristic lines emerging from the hydrogen spectrum. Each of them corresponded to a wavelength predicted by this formula with some integer values for m₁ and ₂. In 1913, Niels Bohr provided an explanation for the observations made in experiments by proposing that each electron in an atom had only certain allowable…arrow_forwardCalculate the frequency, energy (in keV), and wavelength of the Ka x ray for the elements (a) calcium (Ca, Z = 20); (b) cobalt (Co, Z = 27); (c) cadmium (Cd, Z = 48).arrow_forwardWhat are the approximate energies (in keV) of the K and K x rays for scandium?
