Question

Find out the wavelength of photon absorbed by hydrogen atom for excitation from ground state to third excited state.

Answer 1

Answer:10.2Angstrom

Explanation:

Answer 2

Answer:

Given, initially, in a hydrogen atom, the electron is in ground state ∴n=1. Therefore, the energy of the electron in ground state is −13.6eV. Therefore, the energy required to move electrons from ground state to third excited state is 12.75eV.
