Vedclass · Answer

(B) The hydrogen spectrum consists of discrete lines,not a continuous spectrum. $1$. The Lyman series lies in the ultraviolet region. $2$. The Balmer series lies in the visible region. $3$. The Paschen series lies in the infrared region. $4$. The spectral series formula is derived from the Bohr model,not the Rutherford model. Therefore,the correct statement is that the Paschen series is a line spectrum in the infrared region.
