Question

According to the Rydberg equation,the longest wavelength (in nm)in the series of H-atom lines with N₁ = 3 is A)1875 nm B)1458 nm C)820 nm D)656 nm E)365 nm

Quizplus · Accepted Answer

The longest wavelength corresponds to the smallest energy transition, which is from n=4 to n=3 in the Paschen series. Using the Rydberg formula, this transition gives approximately 1875 nm.
