A pulse of light takes 3.00 ns to travel through air from an emitter to a detector. When a piece of transparent material with a length of 35.0 cm is introduced into the light's path, the pulse takes 3.20 ns to travel that same distance. The piece of transparent material is held so that the pulse never changes direction (a) What is the speed of light in the transparent material? 2.56 x m/s (b) What is the index of refraction of the transparent material?
