By calculating its wavelength, show that the first line in the Lyman series is UV radiation.

What is a hydrogen-like atom, and how are the energies and radii of its electron orbits related to those in hydrogen?.

Find the wavelength of the third line in the Lyman series, and identify the type of EM radiation.

Explain why characteristic x rays are the most energetic in the EM emission spectrum of a given element.

Look up the values of the quantities in\[{{\bf{a}}_{\bf{B}}}{\bf{ = }}\frac{{{{\bf{h}}^{\bf{2}}}}}{{{\bf{4}}{{\bf{\pi }}^{\bf{2}}}{{\bf{m}}_{\bf{e}}}{\bf{kq}}_{\bf{e}}^{\bf{2}}}}\], and verify that the Bohr radius a_B is 0.529 x 10^-10 m.
