E₁ = -13,6eV

r₁ = 5,3 x 10⁻¹¹m

h = 6,63 x 10⁻³⁴Js

 

a)

r₃ = n²r₁

 

r₃ = 3² x 5,3 x 10⁻¹¹m = 47,7  x 10⁻¹¹m

 

b)

En = E₁/n²

 

E₃ = -13,6eV/3² = -1,5eV

 

c)

E₂ = -13,6eV/2² = -3,4eV

E₃ = -1,5eV

 

ΔE = -1,5eV - (-3,4ev) = 1,9eV = 3,04 x 10⁻¹⁹J

 

E=  hc/λ => λ = hc/E

 

λ = 6,63 x 10⁻³⁴Js x 3 x 10⁸m/s / 3,04 x 10⁻¹⁹J = 6,54 x 10⁻⁷m
