Question

name the spectal lines which fall in the (a) IR Region (b) Visible region (c) UV Region

Answer 1

(b) The visible spectrum of light from hydrogendisplays four wavelengths, 410 nm, 434 nm, 486 nm, and 656 nm, that correspond to emissions of photons by electrons in excited states transitioning to the quantum level described by the principal quantum numbern equals 2.[1] There are several prominent ultraviolet Balmer lines with wavelengths shorter than 400 nm. The number of these lines is an infinite continuum as it approaches a limit of 364.6 nm in the ultraviolet.
