STANDARD Physics Electromagnetic Spectrum MCQ Question
One requires 11 eV of energy to dissociate a carbon monoxide molecule into carbon and oxygen atoms. The minimum frequency of the appropriate electromagnetic radiation to achieve the dissociation lies in
visible region
infrared region
ultraviolet region
microwave region.
Correct Answer
Detailed Explanation
The energy required is 11 eV, which corresponds to a frequency in the ultraviolet region. Using E = hν, the frequency is calculated to be approximately 2.6 × 10¹⁵ Hz, which falls in the ultraviolet range.
