Question: What is the significance of the Beer-Lambert Law in UV-Vis spectroscopy?

Options:

1. It relates absorbance to concentration and path length.
2. It describes the scattering of light in a medium.
3. It explains the emission spectra of compounds.
4. It determines the molecular weight of a substance.

Correct Answer: It relates absorbance to concentration and path length.

Solution:

The Beer-Lambert Law states that absorbance is directly proportional to the concentration of the absorbing species and the path length of the light.
