Derive a formula that describes the absorption of electromagnetic radiation by matter. Assume that the material contains n atoms per square meter and each atom has a cross sectional area of s. Use No for the number of particles or radiation intensity incident on a unit area. Use N for the number which remain in the radiation beam after traversing a section of the material of thickness x.© BrainMass Inc. brainmass.com October 10, 2019, 1:04 am ad1c9bdddf
