A higher index of refraction means that the wave travels _____________ the speed of light in a vacuum in that medium.

The index of refraction, is defined as the ratio of the speed of light in a vacuum (c = 3x10^8 m/s) to the speed of light in a medium. What is the index of refraction of a medium where the speed of light is 0.7c ? Round off your values to 3 sig. figs.

For light passing across the boundary from higher to lower index of refraction medium, the angle of refraction is always _________________________
