A hydrogen atom (ionisation potential `13.6 eV`) makes a transition from third excited state to first excied state. The enegry of the photon emitted in the process is
A hydrogen atom is in a state of ionization energy 0.85 eV. If it makes a transition to the ground state, what is the energy of the emitted photon.
When an electron in a hydrogen atom makes a transition from 2^("nd") excited state to ground state. It emits a photon of frequency f.The frequency of photon emitted when an electron of Li^("++") makes a transition from 1^("st") excited state to ground state is :
The electron in a hydrogen atom at rest makes a transition from n = 2 energy state to the n = 1 ground state. find the energy (eV) of the emitted photon.
Hydrogen atom in third excited state de-excites to the first excited state. Obtain the expressions for the frequency of radiation emitted in this process. Also determine the ratio of the wavelengths of the emitted radiations when the atom de-excites from the third excited state to the second excited state and from the third excited state to the first excited state.
Electrons in a sample of gas containing hydrogen-like atom (Z = 3) are in fourth excited state. When photons emitted only due to transition from third excited state to second excited state are incident on a metal plate photoelectorns are ejected. The stopping potential for these photoelectorns is 3.95 eV . now, if only photons emitted due to transition from fourth excited state to third excited state are incident on the same metal plate, the stopping potential for the emitted photoelectrons will be appoximetely equal to
A hydrogen atom in a state of binding energy 0.85 eV makes a transition to a state of excitation energy of 10.2 eV . Find the energy and wavelength of photon emitted.
An electron in a hydrogen atom makes a transition from first excited state to ground state . The equivelent currect due to circulating electron :
Electron in hydrogen atom first jumps from third excited state to second excited state and then form second excited state to first excited state. The ratio of wavelength lambda_(1): lambda_(2) emitted in two cases is
A hydrogen atom in state n = 6 makes two successive transition and reaches the ground state in the first transition a photon of 1.13eV is emitted (a) Find the energy of the photon emitted in the second transition (b) what is the value of n in the intermediate state?
