You and a highway patrolman are approaching each other at constant speeds in opposite directions on a straight highway. The patrolman is driving at 60 mph and his radar gun determines your relative speed (the magnitude of the difference between your velocities) to be 100 mph. What is your speed at the time of measurement

What would occur if the index of refraction of a material was less than n=1? the speed of light would increase to a speed larger than the maximum speed of light in a vacuum. the light wave would not bend at all though the material. the light wave would not be able to refract and would instead reflect off of the material. the speed of light would reduce to values close to 0 m/s.
