Post by: Chery on Dec 6, 2016 Radio astronomers often study the radiation emitted by a hydrogen atom from a transition between the two hyperfine levels associated with the ground state. This radiation has a wavelength of 21 cm. What is the energy difference between the hyperfine levels? (1 eV = 1.60 × 10-19 J)
A) 5.9 × 10-6 eV B) 5.9 × 10-25 J C) 1.7 × 10-24 J D) 4.7 × 10-25 J Title: Re: Radio astronomers often study the radiation emitted by a hydrogen atom from a transition between ... Post by: lyall on Dec 6, 2016 Content hidden
