If electrons are excited to `4^(th )` shell in `He^(+)` ion the number of wavelengths emitted by electrons during de-excitation are

The electron in the first excited state (n_(1)=2) of H - atom absorbs a photon and is further excited to n^(th) shell. The de-Broglie wavelength of the electron in this excited state is 1340 pm. Find the value of n .

When an electron is excited to n^(th) energy state in hydrogen, the possible number of spectral lines emitted are

When an electron is excited to n^(th) energy state in hydrogen , the posssible number of spectral lines emitted are

An electron is an excited state of Li^(2 + ) ion angular mometum 3b//2 pi . The de Broglie wavelength of the electron in this state is p pi s_(0) (where a_(0) is the bohr radius ) The value of p is

An electron in the first excited state of if atom obserbed a photon and further excited .The de broglie wavelength of the electron in this state is found to be 13.4Å Find the wavelength of the photon abserbed by the electron in angstroms Also find the longest and the shorted wavelength emitted when this electron de-excited back to the ground state

Once the electron has been exicted to the second excited state, what wavelengths of light can it emit by de - excitation?

The De-Broglie wave length of electron in 1st excited state of He+ nucleus is

Calculate the number of waves made by a Bohr electron in one complete revolution in nth orbit of He^(+) ion, if ratio of de-Broglie wavelength associated with electron moving in n^(th) orbit and 2^(nd) orbit is 2.0 :-
