The frequency of the spectral line emitted when an electron jumps from n = 3 to n = 2 is given by f = ΔE / h.
Q1. The frequency of the spectral line emitted when an electron jumps from n = 3 to n = 2 is given by f = ΔE / h.
Answer: 4.57 × 10¹⁴ Hz
Explanation: Calculate ΔE = E3 - E2 = 1.89 eV, then convert to Joules and divide by h to get f = 4.57 × 10¹⁴ Hz.
