Question

Electrons in a sample of H-atoms make transitions
from state n = X to some lower exited state. The
emission spectrum from the sample is found to
contain only the lines belonging to a particular
series. If one of the photons had an energy of
0.6375 eV, then find out value of X.
(Take 0.6375 eV = * *0.85 eV]​
