Question:
a hydrogen atom in the ground state is excited by radiations of wavelength 975Aamstrong what is the energry state to which the atom is exicted
Answer:
Eph=12448/975 eV
E
ph=12.75V
In hydrogen atom energy level of electron is = 4
If an electron comes from higher energy level (n) to ground state possible value of spectrum line
is = n(n−1)/2
= 4(4−1)/2
=6
