When electron are de-exciting from nth orbit of hydrogen atoms to ground state, 15 spectral lines are formed . The shortest wavelength among these will be :

When an electron falls from 4th orbit to 2nd orbit in hydrogen atom, the spectral line is observed in

When a hydrogen atom is excited from ground state to first excited state then

When a hydrogen atom is excited from ground state to first excited state then

When a hydrogen atom is excited from ground state to first excited state then

When the electron orbiting in hydrogen atom in its ground state moves to the third excited state, show how the de Broglie wavelength associated with it would be affected.

When a hydrogen atom is excited from ground state to first excited state, then

When a hydrogen atom is excited from ground state to first excited state, then
