According to the Rydberg formula, calculate the wavelength λ₁ for the transition from n = 4 to n = 3.

1. λ₁ = R[1/n₁² − 1/n₂²]
2. λ₁ = R[1/n₂² − 1/n₁²]
3. λ₁ = R[1/n₁ − 1/n₂]
4. λ₁ = R[1/n₂ − 1/n₁]

Correct answer: λ₁ = R[1/n₂² − 1/n₁²]

Solution

The Rydberg formula for the wavelength of light emitted during an electron transition is given by λ₁ = 1/R[1/n₁² − 1/n₂²], where n₁ < n₂. Option B correctly represents this formula.
