The emission wavelength of the atoms excited above the ground state is 599.8 nm.
The emission wavelength of the atom is determined by using the following formulas as shown below;
E = hf
E = hc/λ
where;
λ = hc/E
λ = (6.626 x 10⁻³⁴ x 3 x 10⁸) / (3.314 x 10⁻¹⁹)
λ = 5.998 x 10⁻⁷ m
λ = 599.8 x 10⁻⁹ m
λ = 599.8 nm
Thus, the emission wavelength of the atoms is 599.8 nm.
