In a H-atom an electron is in `2^(nd)` excited state and its radius `=4.75Å` calculate the de-broglie wavelength of the electron

Consider an electron in a hydrogen atom, revolving in its second excited state (having radius 4.65Å ). The de-Broglie wavelength of the electron is

Consider an electron in a hydrogen atom, revolving in its second excited state (having radius 4.65 Å ). The de-Broglie wavelength of this electron is :

If the total energy of anelectron in a hydrogen like atom in excited state is -3.4eV ,then the de Broglie wavelength of the electron is

An electron, in a hydrogen like atom , is in excited state. It has a total energy of -3.4 eV, find the de-Broglie wavelength of the electron.

An electron, in a hydrogen like atom , is in excited state. It has a total energy of -3.4 eV, find the de-Broglie wavelength of the electron.
