Austin did a measurement for the speed of light in an experiment. He found that the speed of light is 4.0 x 1018 m/s in air. When Nancy Drew saw his result, she immediately informed him that he made a mistake. How did Nancy know? O Light cannot have a speed. O His result would be correct if the experiment was done under water. O His result would be correct, if the light medium was in vacuum, but not in air. O None of the choices is correct. O Speed of light cannot be greater than 3 x 108 m/s.
