Monochromatic radiation is incident on hydrogen \((\mathrm{H})\) sample which is in ground state. If the hydrogen atoms emit radiation of ten different wavelengths after absorbing the incident radiation, then the wavelength of the incident radiation is (Let \(h c=1242\) eV-nm)
- A \(84.4 \mathrm{~nm}\)
- B \(102.6 \mathrm{~nm}\)
- C \(72.5 \mathrm{~nm}\)
- D \(95.1 \mathrm{~nm}\)
Answer & Solution
Correct Answer
(D) \(95.1 \mathrm{~nm}\)
Step-by-step Solution
Detailed explanation
Given, \(h c=1242 \mathrm{eV} \cdot \mathrm{nm}\) Since, monochromatic radiation is incident on hydrogen sample which is in ground state. Hence, the energy of ground state is given by…
