💡 Solution & Explanation

Let the electron be boosted to nth level, then Number of spectral lines =      n n 1 15 . Given, Or   1 n 1 n 15 2     n = 6 AITS-FT-VII-(Paper-1)-PCM(Sol.)-JEE(Advanced)/19 FIITJEE Ltd., FIITJEE House, 29-A, Kalu Sarai, Sarvapriya Vihar, New Delhi -110016, Ph 46106000, 26569493, Fax 26513942 website: www.fiitjee.com 8 Thus electron is boosted upto 6th energy level from ground state. Therefore H 2 2 1 1 1 35 R 109737 36 n 1             = 9.373  106 cm = 937.3 Å
