✓

Answer

Correct option: B.
Frequency of emitted radiation from a black body goes from a lower wavelength to higher wavelength as the temperature increases
b
When temperature is increased, black bodyemit high energy radiation, from higher wavelength to lower wavelength . Rydberg constant has unit of length i.e. $cm^{-1}$
