The wavelength of the third line in the Lyman series, and identify the type of EM radiation
In this series, the spectral lines are obtained when an electron makes a transition from any high energy level (n=2,3,4,5... ). The wavelength of light emitted in this series lies in the ultraviolet region of the electromagnetic spectrum.
1 / lambda = R(h)* ( [tex]\frac{1}{(n1)^{2} }[/tex] - [tex]\frac{1}{(n2)^{2} }[/tex])
= 109678 ( [tex]\frac{1}{1^{2} }[/tex] - [tex]\frac{1}{3^{2} }[/tex] )
= 109678 (8/9)
Lambda = 9 / (109678 * 8 )
= 102.6 * [tex]10^{-9}[/tex] m = 102.6 nm
