List of top Chemistry Questions on Spectroscopy asked in NEET (UG)

Given below are two statements:
Statement I: The Balmer spectral line for H atom with lowest energy is located at \( \frac{5}{36} R_H \, \text{cm}^{-1} \).
(\( R_H \) = Rydberg constant)
Statement II: When the temperature of blackbody increases, the maxima of the curve (intensity and wavelength) shifts to shorter wavelength.
In the light of the above statements, choose the correct answer from the options given below:

The UV-visible absorption bands in the spectra of lanthanoid ions are ‘X’, probably because of the excitation of electrons involving ‘Y’. The ‘X’ and ‘Y’, respectively, are :
