Calculate the energy involved in the transition of an electron in the hydrogen atom from level 5 to level 2. Use the energy to calculate the wavelength of electromagnetic radiation emitted. However, do not change the fractions to lowest common denominator. Determine (1/nf^2 - 1/ni^2)
E = 2.180E-18 x (1/4 - 1/25) where
1/4 is 1/2^2 and 1/25 = 1/5^2. Solve for Energy.
E = hc/wavelength. Solve for wavelength
