Multiple choice In which case, the wavelength emitted is minimum? An electron jumps from 2nd to 1st level An electron jumps from 3rd to 2nd level An electron jumps from 4th to 3rd level An electron jumps from 5th to 4th level Reveal answer Fill a bubble to check yourself A Correct answer Explanation Applying the Rydberg's equation 1/λ = R0[1/n12 - 1/n22] . We get 1/λ = R0 [3/4] or λ = 1.33/R0. This value of wavelength is the least among the given options.
