problem 7 MATLAB

Problem (7): The transmission of light through a transparent solid can be described by the equation where I, is the transmitted intensity, 10 is the intensity of the incident beam, is 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 interface and the beams are transmitted through air (n+1) hr." isthmitted though specimens ofatransparentsolid of various lengths are R =1-1 where n is the index of refraction for the transparent solid. Experiments measuring n +1 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 W/m2 0.5 4.2 1.2 4.0 2.2 3.6 4.5 2.9 6.0 2.5 cm 3.8 Use this data and curve fitting to determine the absorption coefficient and index of refraction of the solid
