. What will be the longest wavelength line in Balmer series of spectrum
(a) 546 nm
(b) 656 nm
(c) 566 nm
(d) 556 nm
Best Answer
Correct Option Is (b) :
Explanation :
The longest wavelength refers to lowest energy.
Rydberg’s constant, RH = 109677 cm-1
= 115233= 6.56 10-5 cm = 656nm
Hence, the correct answer is b.
