Problem 6.28

For the case of atomic hydrogen find: (a) the wavelengths of the first three lines of the Balmer series; (b) the minimum resolving power λ/δλ\lambda / \delta \lambda of a spectral instrument capable of resolving the first 20 lines of the Balmer series.

Reveal Answer
(a) 657,487 and 434nm;434 \mathrm{nm} ; (b) λ/δλ≈1.5⋅103\lambda / \delta \lambda \approx 1.5 \cdot 10^{3}
