List of top Physics Questions on Atomic Spectra asked in CUET (UG)

Energy levels \(A\), \(B\), \(C\) of a certain atom correspond to increasing values of energy \((E_A<E_B<E_C)\). If \(\lambda_1\), \(\lambda_2\) and \(\lambda_3\) are the wavelengths of radiations corresponding to the transitions \(C\to B\), \(B\to A\) and \(C\to A\) respectively, the relation between these wavelengths can be written as

What is the ratio of the shortest wavelength present in the Lyman series of hydrogen spectral emissions to the shortest wavelength present in the Balmer series?

The energy diagram of a hydrogen atom is given below. Arrange the wavelengths corresponding to different emissions in increasing order.
