At what temperature the transitional kinetic energy of atomic hydrogen equal that for `n_2` =1 to `n_2` =2 transition.

At which temperature will the translational kinetic energy of H-atom equal to that for H-atom of first line Lyman transition? (Given N_(A)=6xx10^(23) )

Consider a hydrogen-like ionized atom with atomic number with a single electron. In the emission spectrum of this atom, the photon emitted in the 2 to 1 transition has energy 74.8 higher than the photon emitted in the 3 to 2 transition. The ionization energy of the hydrogen atom is 13.6. The value of is __________.

The frequency corresponding to transition n = 1 to n = 2 in hydrogen atom is.

Given that in H-atom the transitioin energy for n=1 to n=2 is 10.2eV, the energy for the same transition in Be^(3+) is

By giving energy to a hydrogen atom in energy state n=1. If the potential energy of the atom in n=1 state be -13.6 eV , calculate (a) potential enregy in state n=4, (b) energy absorbed by the atom in the transition, and (c) wavelength of radiation emitted during transition from n=4 to n=1 state.

what are the frequency and wavelength of a photon emitted during a transition from n = 5 state to the n =2 state in the hydrogen atom?

An electron in a hydrogen atom makes a transition such that its kinetic energy increases, then

Electron in a hydrogen atom makes a transition from higher energy states to n=2. Calculate the maximum possible wavelengths in this transition.

The electron in a hydrogen atom at rest makes a transition from n = 2 energy state to the n = 1 ground state. Assuming that all of the energy corresponding to transition from n = 2 to n = 1 is carried off by the photon. By setting the momentum of the system (atom + photon) equal to zero after the emission and assuming that the recoil energy of the atom is smaller compared with the n = 2 to n = 1 energy level separation , find the energy of the recoiling hydrogen atom.
