Question

Hydrogen sample is in Ist excited state A photon of
energy 8eV is used to excite the hydrogen sample.
Find the de-Broglie wavelength of the electron.
What will be m in de broglie equation

Answer 1

Answer:

Hydrogen sample is in first excited state A photon of energy 4.9 eV in used to excite the hydrogen sample then the de-Broglie wavelength of the electron is:

Q2

The De-Broglie wave length of electron in second exited state of hydrogen atom is

Q3

If the total energy of an electron in a hydrogen atom in excited state is -3,4 eV, then the de Broglie wavelength of the electron is :-
