- In extreme-temperature environments, such as those existing in a solar corona, atoms may be ionized by undergoing collisions with other atoms. One example of such ionization in the solar corona is the presence of C5+ ions, detected in the Fraunhofer spectrum. (a) By what factor do the energies of the C5+ ion scale compare to the energy spectrum of a hydrogen atom? (b) What is the wavelength of the first line in the Paschen series of C5+ ? (c) In what part of the spectrum are these lines located?arrow_forwardCalculate the wavelength of the third line of the Paschen series for hydrogen.arrow_forwardIf, in 1 1 = Ry - you set ni = 1 and take n2 greater than 1, you generate what is known as the Lyman %3D series. Find the wavelength of the first mem- ber of this series. The value of ħ is 1.05457 × 10¬34 J.s; the Rydberg constant for hydrogen is 1.09735 × 10’ m¬'; the Bohr radius is 5.29177 × 10¬1" m; and the ground state energy for hydrogen is 13.6057 eV. Answer in units of nm. Consider the next three members of this se- ries. The wavelengths of successive members of the Lyman series approach a common limit as n2 → ∞. What is this limit? Answer in units of nm.arrow_forward
- Use Balmer’s formula to calculate (a) the wavelength, (b) the frequency, and (c) the photon energy for the Hg line of the Balmer series for hydrogen.arrow_forwardFrom the energy-level diagram for hydrogen, explain the observation that the frequency of the second Lyman-series line is the sum of the frequencies of the first Lyman-series line and the first Balmer-series line.This is an example of the empirically discovered Ritz combination principle. Use the diagram to find some other valid combinations.arrow_forwardCalculate the Kα and Kβ wavelengths for He and Li.arrow_forward

- Find the relation between spontaneous emission lifetime and cross section for a simple atomic transition.arrow_forwardFor a given value of l , what are the allowed values of ml ? What are the allowed values of ml for a given value of n ? Give an example in each case.arrow_forwardConsider only the Lyman, Balmer and Paschen series for the energy diagram provided for an unknown element. If the visible spectrum Lies between 370 nm to 750 nm, determine the number of different energies that would be observed from the unknown element which ally in the infra rated spectrum.
