Question

Ionisation potential of the hydrogen atom is 13.6 eV. Hydrogen atoms in the ground state are excited by monochromatic radiation of photon energy 12.1 eV. The number of spectral lines emitted by hydrogen atoms according to Bohr's theory will be:

Options:

Answer:

C

Solution:

$12.1 = 13.6 (1 - \frac{1}{9})$ , so atoms reach $n = 3$ . Lines $=^{3} C_{2} = 3$ .
