What is the energy in J of a photon of light with a frequency of 1060 Hz? Please sure to answer with correct number of significant figures and use unit after the number. Explain what is meant by atomic (line) spectrum. (Give the experimental conditions necessary for its observation.) Then use Planck's quantum theory to explain why the spectrum is not continuous.
