Question

Bohr's theory explained spectrum of one electron species. The wavelength of series limit in Lyman series of Hydrogen spectrum is equal to a. O 684 A b. O 3648 A c. O 1216 Aº
d.
O 912 A w​

Answer 1

Answer:

When n = 3, Balmer's formula gives λ = 656.21 nanometres (1 nanometre = 10−9 metre), the wavelength of the line designated Hα, the first member of the series (in the red region of the spectrum), and when n = ∞, λ = 4/R, the series limit (in the ultraviolet).

c. O 1216 Aº
