    Absorption Spectra and the Beer-Lambert Law. ɛ Purpose : Understanding of Beer –Lambert Law Introduction : When light passes through the colour solution ‚ the molecules of the solution absorb the quantity of light at a particular wavelength . The amount of light which is absorbed by solution depend on two things. 1. The length of the pathway of light 2.Concentration of colour solution. These are all explained by the Beer-Lambert Law. Absorbance (A) = ɛcl

    • 2 Pages

    Beer-Lambert Law Relationship Between Molar Concentration and Absorbance Solution colour results from the absorbance of some light wavelengths by solutes dissolved in solution‚ while allowing other wavelengths to pass through (transmittance). The combination of the remaining wavelengths that pass through results in the colour of the solution. A colorimeter can be used to determine the amount of light at a particular wavelength that is absorbed/transmitted by a solution. Depending on the concentration

    Charles’s LawLab Report Charles’ Law: Assuming that pressure remains constant‚ the volume and absolute temperature of a certain quantity of a gas are directly proportional. Mathematically‚ this can be represented as: Temperature = Constant x Volume or Volume = Constant x Temperature or Volume/Temperature = Constant Substituting in variables‚ the formula is: V/T=K Because the formula is equal to a constant‚ it is possible to solve for a change in volume or temperature using a proportion

    The Beer-Lambert LawWhat the Law looks likeYou will find that various different symbols are given for some of the terms in the equation - particularly for the concentration and the solution length. I’m going to use the obvious form where the concentration of the solution is "c" and the length is "l". | | Note:  That’s obviously "l" for length. The font I’m using won’t distinguish between "l" for length and a capital letter "I" (for Intensity). That problem disappears in the equation below - where

    Coulomb’s Law 1. Objective - To study the validity of Coulomb’s law on a simple electroscope. This will be split into two parts; first measuring the the force as a function of distance‚ and second we will look at how the magnitude and sign of the charges affect the force. 2. Theory- As is well known‚ like charges repel and opposite charges attract. That being said‚ the strength of those forces also depends on the distance between the two charges
