Per NCERT Table 2.3, in the hydrogen-atom spectrum the BALMER series corresponds to transitions ending in n₁ = 2 and lies in which spectral region?
AInfrared
BX-ray
CVisible
DUltraviolet
Answer & Solution
Correct answer: C. Visible
Per NCERT Table 2.3, Balmer (n₁ = 2) is the only series that lies in the visible region. Lyman is UV; Paschen, Brackett, Pfund are IR.
