Chemistry - Atomic Structure Question with Solution | TestHub
In a hydrogen like sample two different types of photons A and B are produced by electronic transition. Photon has it's wavelength in infrared region if photon A has more energy than B, then the photon A may belong to the region
Options:(select one or more)
Answer:
Solution:
Explain Question:
Identifying spectral regions based on photon energy.
Concept:
Hydrogen Spectrum and Energy Levels.
Solution:
In a hydrogen-like atom, energy levels are grouped into series (Lyman, Balmer, Paschen, etc.). The energy of a photon depends on the gap between these levels. If photon B is in the infrared region, photon A (which has more energy) could be in a higher energy region like visible or ultraviolet.
Calculation:
Energy (E) is inversely proportional to wavelength (λ). The order of regions by increasing energy is:
Infrared < Visible < Ultraviolet. Since Energy of A > Energy of B (Infrared), A could be in the Infrared, Visible, or Ultraviolet region. Among the given choices, both 1, 2, and 3 are physically possible, but in standard multiple-choice contexts for "may belong," we recognize that any region with higher energy than IR is a valid answer.
