Three photons coming from excited atomic-hydrogen sample are picked up. Their energies are 12.1eV, 10.2eV and 1.9eV. These photons must come from
Text Solution
Verified by ExpertsThe correct answer is:
D
12.1 = E(n = 3) – E (n = 1)
10.2 = E(n = 2) – E (n = 1)
1.9 = E(n = 3) – E (n = 2)
At least two atoms must be enveloped as there cannot be two transition from same level from same atom.
