Ionisation potential of hydrogen atom is 13.6 eV. Hydrogen atom on the ground state rarely excited by monochromatic radiation of photon 12.1 eV. The special line emitted by a hydrogen atom according to Bohr's theory will be
A) one
B) two
C) three
D) four
Correct Answer:
C
Solution :
From the relation \[{{E}_{3}}-{{E}_{1}}=(-1.5)-(-13.6)+12.1\]
