Question

Calculate the wavelength of light emitted when each of the following transitions occur in the hydrogen atom.



n = 5 to n = 3



_____________ nm

(Answer should be reported with 4 sig figs)

Answer 1

λ^-1= R(n^-2_final-n^-2_initial)

n _final=3 while n _initial=5

R=1.097*10⁷m^-1

λ^-1=1.097*10⁷(3^-2-5^-2)m^-1

λ^-1=7.8009*10⁵m^-1

λ=(7.8009*10⁵m^-1)^-1

λ=1.282*10^-6m
