Beer Attenuation
How I can solve this question please?
the attenuation coefficient of muscle is 800cm-1 in the wavelength emitted by the CO2 laser (1.06 multiplied by 10 to -5). calculate the thickness of the muscular layer that absorbs 90% of the energy of the light from this laser is response 0.03 mm but how I can use the given numbers and put them into the formula of Beer-Lambert law, but I have put the number 800cm-1 as it is or means place of M, or I have to turn it into something
I / I '= e ^ (- μ x), where = intensity of the beam emerging' = original beam intensity μ = x = As thickness of the energy attenuation coefficient is proportional to the intensity, putting information given in this formula, noting that 90% is absorbed by what 10% remains as the means / I '= 0.10 => 0.1 = e ^ (- 800 x), where x = thickness in cm. => In (0.1) = – 800x => On 1 – 10 = – 800 x => x = (ln 10) / 800 = 0.003 cm = 0.03 mm. [Note: the wavelength is not needed here.]
