Question

In a hydrogen atom, the electron is in nth excited state. It may come down to second excited state by emitting ten different wavelengths. What is the value of n:

G1 Physics · Accepted Answer

Step 1: For transitions among n populated levels, the maximum number of distinct emission lines is n(n−1)/2, subject to the initial/final levels stated in the question. Step 2: Use the given excitation to identify n. Final: A: 6.
