Question

What electron transition in a hydrogen atom,starting from the orbit n=7 will produce infrared light of wavelength 2170nm?( RH=1.09677×107m−1)

Answer 1

The formula defining the energy levels of a Hydrogen atom are given by the equation: E = -E0/n2, where E0 = 13.6 eV (1 eV = 1.602×10-19 Joules) and n = 1,2,3… and so on. ... For example an electron in the ground state has an energy of -13.6 eV.

Answer 2

Answer:

n= 7 to n= 4

Explanation:

Hence, Electronic transition from n=7 to n=4 in a hydrogen atom will produce infrared light of wavelength of 2170nm
