Question

When the electron orbittingin the hydrogen atom in its ground state
moves to the third exciting state show how the debroglie wavelength
assosciated with it changes

Ved Prakash Lakhera · Accepted Answer

The energy of nth state of hydrogen atom is given by,               En = -13
6n2eVSo energy od ground state    E1 = -13
612eV=-13
6eVand energy of third state      E3 = -13
632eV = -1
51eVChange in energy ∆E=  E3-E1 =-1
51+13 6 eV=12 09eV=12 09×1
6×10-19JTherefore change in wavelength ∆λ = hc∆E=6
63×10-34×3×10812 09×1 6×10-19=1037
