Calculate the wavelength of light emitted in the Balmer region, where n i = 5. Report your numerical answer in units of nm. Use sig figs.?

Rydberg constant, R = 1.097 × 10⁷ /m
For Balmer series, n(f) = 2

Rydberg formula: 1/λ = R {[1/n(f)²] - [1/n(i)²]}
1/λ = (1.097 × 10⁷) × [(1/2²) - (1/5²)]
λ = 1 / {(1.097 × 10⁷) × [(1/4) - (1/25)]}
λ = 4.34 × 10⁻⁷ m
