Lambert-Beer's law, also known as Beer-Lambert law, describes the absorption of light by a medium. Mathematically, it can be expressed as ( A = \epsilon c l ), where ( A ) is the absorbance, ( \epsilon ) is the molar absorptivity, ( c ) is the concentration of the absorbing species, and ( l ) is the path length of the light through the medium. The derivation begins with the understanding that light intensity decreases exponentially as it travels through an absorbing medium, leading to the differential equation ( dI = -\epsilon c I , dl ). Integrating this equation from 0 to ( l ) results in the exponential form of the law, relating absorbance directly to concentration and path length.

A formula is defined as a mathematical expression of a natural law. A formula is a combination of numbers and symbols used to describe how something works.
Beer's Law, also known as the Beer-Lambert law, relates the attenuation, or reduction, of light to the properties of the material it passes through. It's mainly related to the BGK model, which is a mathematical model that helps describe collisions of particles.
The Lambert-Beer law is the base of absorption spectrophotometry.

you can make your own mathematical law, but it should be very similar and related to the original mathematical law. also there is an another issue, sometimes your own mathematical law will not work, so it is very important and better to use the original mathematical law to avoid mistakes and to get the correct answer.
The Beer-Lambert Law is expressed as A = εlc, where A represents the absorbance of light at a certain wavelength by a sample, ε is the molar absorptivity of the substance, l is the path length of the sample, and c is the concentration of the absorbing species.
No, a substance that does not obey Beer-Lambert law cannot be accurately analyzed spectrophotometrically. The Beer-Lambert law is the fundamental principle that relates the concentration of a solute in a solution to the absorbance of light. If this relationship is not followed, the spectrophotometric analysis will not provide reliable results.
Benford's law is obtained as maximum entropy distribution of balls in boxes under the assumption that the number of balls in a box can be 1,2,3....9. For derivation see Oded Kafri "entropy principle in direct derivation of Benford's law" at arxive (2009) .
The Beer-Lambert law Absorbance = (extinction coefficent)(pathlength of light)(concentration) allows you to measure the absorbance of sample in a UV spec, and change the rate from absorbance units / time to change in concentration / time. the pathlength of light being the width of the cuvette and the extinctin coefficent being specific to the product molecule.
The law is not valid at high concentration; more details at this link.
The Bavarian beers list typically includes traditional German beer styles such as lagers, wheat beers, and bocks. These beers are known for their quality and adherence to the German Beer Purity Law, which limits ingredients to water, barley, hops, and yeast.
