AIPMT PRELIMS 2006 Physics Bohr's Model MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Ionization potential of hydrogen atom is 13.6 eV. Hydrogen atoms in the ground state are excited by monochromatic radiation of photon energy 12.1 eV. According to Bohr's theory, the spectral lines emitted by hydrogen will be:
A
two
B
three
C
four
D
one
Correct Answer
Option B
Detailed Explanation
The energy difference between the ground state and the first excited state is 13.6 eV - 12.1 eV = 1.5 eV. This energy allows transitions that result in two spectral lines.
