Problems Derive η2η1=v1v2frac{eta_2}{eta_1}=frac{v_1}{v_2} where ηieta_i is the refractive index of material ii and viv_i is the speed of propagation in material ii . Suppose light of frequency FFin a vacuum enters a medium with refractive index aa. What is the light’s frequency in this new medium? Joe shined a laser through a medium with a […]
