4. ### Calculate the energy of a photon emitted when an electron in a hydrogen atom undergoes a transition from n =?

We can find the energy (E) from the wavelength (w) by: E = hc/w where h is Planck's constant, 6.625 * 10**-34 joule-sec. and c the speed of light which is 3.0 * 10**8 meters per sec. so E = hc/w We can find w from the lower (L) and upper (U...
