Solving the ultraviolet catastrophe (i.e., explaining why everyday objects do not radiate UV light), led directly to which of the following rationalizations? A) The frequencies of atomic vibrations needed to be restricted to a discrete set of values B) Pauli's exclusion principle C) The kinetic energy of electrons depended on the intensity, rather than the frequency of light D) The Aufbau principle E) Light exhibits both particle-like and wave-like behavior

Calculate the photon energy (in kJ/mol) for the single Li emission and the two Na emission wavelengths. To accomplish this, first calculate the energy in units of J/photon from Equation (4) and then multiply the result by Avogadro’s number to express the energy in J/mol of photons. Lastly, divide by 1000 to convert this result to units of kJ/mol.
