Question

With respect to air the refractive indices of water and benzene are 1.33 and 1.5 resp calculate index of benzene with respect to water

Answer 1

refractive index of water with respect to air = 1.33=refractive index of water÷refractive index of air                                                                 (1)

Similarly refractive index of benzene with respect to air=1.5=ref. index of benzene÷ refractive index of air                                                            (2)

eq(2)/(1)

ref. index of benzene/ref. index of water=1.5÷1.33=1.127
