A photon of wavelength 568 nm is incident on the molecule. This photon cannot be absorbed by this molecule. What photon energy is required to raise this molecule from its electronic ground state to its first excited state. The diagram, illustrates molecular energy levels as discussed in this course. Arrow 1 represents absorption of light.
None is correct.
The graph below shows a computer simulation of the count rate for absorption of , g -ray photons by lead, as a function of the thickness of lead. Ingested 131 I has been used medically to treat diseased thyroid tissue. He needs to know the electrical conductance of the salt solution. The symbol G s represents the conductance of the solution. A to D is NOT correct.
