The shortest wavelength of the spectral lines in the Lyman series of hydrogen spectrum is 915 Ã… . The longest wavelength of spectral lines in the Balmer series will be _____ Ã… .

Step-by-step solution

Shortest, hc =-13.6 ( 1 n ₁^2 - 1 n ₂^2 ) E ; hc ₀ =-13.6(1) Balmer Series : aligned & hc ₁ =-13.6 ( 1 2^2 - 1 3^2 ) & hc ₁ =-13.6 ( 1 4 - 1 9 ) aligned aligned & hc ₁ =-13.6 ( 5 36 ) & -13.6 ₀ ₁ =-13.6 5 36 & ₁= ₀ 36 5 = 915 36 5 =6588 aligned
