Question

Why must the radiation source for fluorescence spectrometry be more powerful than for absorption spectroscopy?

a.

Because the magnitude of the output signal is proportional to the power of the incident radiation

b.

Because the sample won't fluoresce if the incident radiation is of low power

c.

To allow for scattering by the sample

d.

None of the above

Answer: (a).Because the magnitude of the output signal is proportional to the power of the incident radiation
