The transmission of light through a transparent solid can be described by the equation: where Ir is the transmitted intensity, Io is the intensity of the incident beam. s the absorption coefficient, L is the length of the transparent solid, and R is the fraction of light which is reflected at the interface. If the light is normal to the is no )2 where n is the index interface and the beams are transmitted through air, Rere n is the index of refraction for the transparent solid. Experiments measuring the intensity of light transmitted through specimens of a transparent solid of various lengths are given in the following table. The intensity of the incident beam is 5 watts/m2 ngthe intensity of light traR=( L(cm) | 0.5 | 1.2 | 1.7 | 2.2 | 4.5 | 6.0 ir (watts/m2)|4.214.0 | 3.8 | 3.6 | 2.9 Figure 3: Data Table Problem 4 Use this data and curve fitting to determine the absorption coefficient and index of refraction of the solid
