An electron undergoes a transition from an initial (ni) to a final (nf) energy state. The energies of the (ni) and (nf) energy states are -1.360 x 10^-19 J and -8.720 x10^-20 J, respectively. Calculate the wavelength of the light in nanometers corresponding to this transition. You can use the following values for your calculations: Planck's constant (h) = 6.626x10^-34 Jxs, speed of light (c) = 2.998x10^8 m/s, and 1m=10^9nm.
