AIIMS 2019 Physics Energy Levels and Spectra Assertion Reason Question
Assertion : Hydrogen atom consists of only one electron but its emission spectrum has many lines.
Reason : Only Lyman series is found in the absorption spectrum of hydrogen atom whereas in the emission spectrum, all the series are found.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
When an electron in an atom absorbs energy, it can transition to a higher energy level, creating an excited state. As it returns to its ground state, it may pass through various intermediate energy levels, emitting photons of different wavelengths, which results in a spectrum with multiple lines. This phenomenon is described by the emission spectrum of the atom, where each line corresponds to a specific transition between energy levels. The other options are not applicable as they do not provide relevant information or alternative answers related to the concept of electron transitions and spectral lines.
