1.11. A sample of ordinary hydrogen (iH) gas in a discharge tube was seen to emit the usual Balmar spectrum. On careful examina- tion, however, it was found that the H. line in the spectrum was spit into two fine lines, one an intense line at 656.28 nm, and the other a faint line at 656.04 nm. From this, one can conclude that jahir.iitb@gmail.com physicsguide.in/net Sk Jahiruddin Atomic Molecular: June 2020 the gas sample had a small impurity of [TIFR 2015] (a) H (b) H (c) H (d) H20
