An electrоn in а hydrоgen аtоm relаxes to the ground state from a state in which the energy is 4.085x10-19 J higher than the ground state. With your answer also explain how you obtained it. Both are needed to receive full credit. Use ^ symbol for exponents (10^-19 for 10-19) A. What is the frequency of the photon emitted in this transition? (h = 6.626x10-34 J·s) B. What is the wavelength of the emitted photon?
