Ionization equation for hf
WebUsing the wave equation, the wavelength of the emitted, or absorbed, radiation can be related to the energy difference by the equation: $ \lambda=\frac{h c}{E_2-E_1} $ This equation shows that the larger the difference in energy of two levels $\Delta E$, the shorter the wavelength $\lambda$ and vice versa WebTable of Acids with Ka and pKa Values* CLAS * Compiled from Appendix 5 Chem 1A, B, C Lab Manual and Zumdahl 6th Ed.
