Question

Which of the following is not a limitation of Beer
Lambert's law, which gives the relation between
absorption, thickness, and concentration?
Concentration must be
lower
Radiation must have higher
bandwidth
Radiation source must be
monochromatic
Does not consider factors other than thickness​

Answer 1

Option (b) is the correct answer

Radiation must have higher bandwidth

Explanation:

• Beer's law is derived from the assumption that light is monochromatic.

• Its band width increases and it creates deviation.

• There is high concentration and deviation in absorptivity coefficients.

• According to this law scattering of light is due to the particulates present in the sample.

• This law will not be obeyed if photons of light striking the detector do not have the chance of equal absorbance.
