Discussion Questions: Question 1: It can be said that the lines in the visible region can be deduced using the Balmer series, since it is only series which can used to see where the lines belong too. Using Balmer series when m = 2, the n 1 value for the hydrogen is also 2. For the red spectral line the n 2 value should be n=3, when it is green-blue, n=4, for the blue, n=5, and violet should be n=6. Question 2: Colour Wavelength (nm) Wavelength(cm) Red 681.36 6.8136E-5 Yellow 5.75 5.75E-5 green/blue 459.74 4.5974E-5 Violet 383.756 3.83756E-5 g = G ± 1 ² g 1 ³ g ´ 1 6.8136 µ¶ −5 · = G ( 1 2 g 1 3 g ) 1 6.8136E −5 · = G (0.1388888888) G ≈ 105677.77
