The Rydberg constant for hydrogen is 1.097xx10^(7)m^(-1) . Calculate the short and long wavelength limits of Lyman series.
Rydberg constant is
The wavelength of the first line of Balmer series is 6563 Å . The Rydbergs constant fro hydrogen is about
In an ordianary atom, as a first approximation, the motion of the nucleus can be ignored. In a positronium atom a positronreplaces the proton of hydrogen atom. The electron and positron masses are equal and , therefore , the motion of the positron cannot be ignored. One must consider the motion of both electron and positron about their center of mass. A detailed analyasis shows that formulae of Bohr's model apply to positronium atom provided that we replace m_(e) by what is known reduced mass is m_(e)//2 . If the Rydberg constant for hydrogen atom is R , then the Rydberg constant for positronium atom is
If R is the Rydberg's constant for hydrogen the wave number of the first line in the Lyman series will be
Consider an atom made up of a protons and a hypothetical particle of triple the mass of electron but having same charge as electron. Apply bohr model and consider all possible transition of this hypothetical from second excited state to lower states.The possible wavelengths emitted is (are) (given in term of the Rydberg constant R fr the hydrogen atom)
Imagine an atom made up of a proton and a hypotnerical particle of double the mass of the electron but having the same charge as the electron. Apply the Bohr atom model and consider all possible transitions of this hypotnetical photon that will be emitted has wavelength lambda (given in terms of the Rydberg constant R for the hydrogen atom) equal to
Imagine an atom made of a proton and a hypothetical particle of double the mass of the electron but having the same change as the electron. Apply the Bohr atom model and consider all possible transitions of this hypothetical particle of the first excited level. the longest wavelength photon that will be emitted has wavelength [given in terms of the Rydberg constant R for the hydrogen atom] equal to
The ionisation energy of hydrogen atom is 13.6 eV. Calculate Rydberg's constant for hydrogen.
