Atomic theory explains that all matter is made up of tiny particles called atoms. This scientific theory was developed before scientists could view individual atoms with powerful microscopes. How could the development of a new technology affect this theory?

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.
