NEET Physics Hydrogen Atom MCQ Question
Type: MCQ-numerical-Hard-Class 12
Calculate the wavelength of the photon emitted when an electron transitions from the n=4 orbit to the n=2 orbit in a hydrogen atom.
A
486 nm
B
410 nm
C
656 nm
D
434 nm
Correct Answer
Option A
Detailed Explanation
The transition from n=4 to n=2 corresponds to the Balmer series in the hydrogen spectrum. Using the relation between energy levels and wavelength, the wavelength is computed as 486 nm.
