What is the relationship between the light emitted by an atom and the energies of the electrons in the atom?
A) The larger the atom, the greater the number of electrons and therefore the greater the frequency of a light.
B) The energies of the electrons of an atom are directly proportional to the wavelength of light emitted and therefore inversely proportional to the frequency of the light emitted.
C) The greater the frequency of a photon of light, the greater the energy packed into that photon.
D) The light emitted by an atom is a function of its nuclear density and its ability to absorb and reflect various wavelengths of light from the electromagnetic spectrum.
