Step 1: Understand that the Beer-Lambert Law relates to how light interacts with a substance.
Step 2: Know that 'A' stands for absorbance, which measures how much light is absorbed.
Step 3: Recognize that 'ε' (epsilon) is the molar absorptivity, a constant that indicates how strongly a substance absorbs light at a specific wavelength.
Step 4: Identify 'c' as the concentration of the substance in the solution, usually measured in moles per liter.
Step 5: Learn that 'l' is the path length, which is the distance the light travels through the substance, typically measured in centimeters.
Step 6: Put it all together in the equation A = εcl to understand how these factors relate to each other.
