Hydrogen atoms are excited from ground state to the principal quantum number 5. Number of spectral lines observed will be
Atomic hydrogen is excited to the nth energy level . The maximum number of spectral lines which it can emit while returning to ground state,is:
An atom has x energy level , then total number of lines in its spectrum are :
Hydrogen atoms are excited from ground state of the principle quantum number 4 . Then the number of spectral lines observed will be
The electron in hydrogen atom in a sample is in n^(th) excited state, then the number of differrent spectrum lines obtained in its emission spectrum will be
Hydrogen atom in ground state is excited by a monochromatic radiation of lambda = 975 Å . Number of spectral lines in the resulting spectrum emitted will be
A hydrogen atom is excited up to 9th level. The total number of possible spectral lines emitted by the hydrogen atom is
