Question

1. of the four measured hydrogen spectrum lines, which line corresponds to the transition n = 3 to n = 2, and from n = 4 to n = 2, and so on from n = 6 to n = 2?

n=3, n=2 is h-alpha, n=4, n=2 is h-beta, n=5, 2 is h-gamma, and n=6, n=2 is h-delta

Explanation:

The Balmer series in the hydrogen spectrum corresponds to electron transitions to the \( n = 2 \) energy level. The lines are named as follows: \( n = 3 \to n = 2 \) is H - alpha, \( n = 4 \to n = 2 \) is H - beta, \( n = 5 \to n = 2 \) is H - gamma, and \( n = 6 \to n = 2 \) is H - delta. So the lines corresponding to \( n = 3 \to n = 2 \), \( n = 4 \to n = 2 \), \( n = 5 \to n = 2 \), \( n = 6 \to n = 2 \) are H - alpha, H - beta, H - gamma, H - delta respectively.

Answer:

• \( n = 3 \to n = 2 \): H - alpha
• \( n = 4 \to n = 2 \): H - beta
• \( n = 5 \to n = 2 \): H - gamma
• \( n = 6 \to n = 2 \): H - delta
