Is refractive index, the ability of a medium to bend/slow down the light? If refractive index of diamond is 2.42,does it mean light travels 2.42 times faster in air than in diamond?

refractive index tells us how fast is light travelling in that medium with respect to speed of light in vaccum/air ..... By this we can say that refractive index is the ability of the medium to slow and bend the light.......Regards
