the wavenumber of a given transition is 2000 cm^-1. the region of electromagnetic spectrum corresponding to this transition is
Answer:
The wavenumber of a transition is directly proportional to the energy of the transition and inversely proportional to the wavelength of the corresponding electromagnetic radiation.
A wavenumber of 2000 cm^-1 corresponds to an energy of 20000 cm^-1 * h * c, where h is Planck’s constant and c is the speed of light.
In the electromagnetic spectrum, the region corresponding to transitions with energies in the range of the infrared region is typically between 4000 cm^-1 to 400 cm^-1. Since the wavenumber of the given transition is 2000 cm^-1, it lies in the infrared region of the electromagnetic spectrum.
So, the region of the electromagnetic spectrum corresponding to the transition with a wavenumber of 2000 cm^-1 is the Infrared region.
