Select the one among the following transitions in hydrogen atom, which gives an absorption line of lowest frequency:
Correct answer: C. n = 4 to n = 6
- A. n =1 to n = 3
- B. n = 2 to n = 3
- C. n = 4 to n = 6
- D. n= 3 to n = 4
Explanation
Transition from n = 4 to n = 6 involves the largest energy change, resulting in the absorption of a photon with the lowest frequency and longest wavelength among the given options. This is because the energy of a photon is inversely proportional to its wavelength, and larger energy gaps correspond to lower-frequency transitions.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
