Spectroscopy

Statement I: The Balmer series corresponds to electronic transitions where the electron falls to the n=2 energy level. The lowest energy transition in the Balmer series is from n=3 to n=2. The wavenumber ( ) for this transition can be calculated using the Rydberg formula:

For the lowest energy Balmer transition ( =2, =3):

The wavenumber is indeed cm . Thus, statement I is true.
Statement II: Wien's displacement law states that the wavelength of maximum intensity for blackbody radiation is inversely proportional to its temperature. As the temperature increases, the wavelength of maximum intensity shifts to shorter wavelengths. Thus, statement II is true.
