The speed of light in vacuum will be doubled
- The speed of light in vaccum is given by the relation
Speed = Distance / Time
- The relation shows that the speed of light is directly proportional to the distance
- Distance is measured by length and if unit of length is doubled distance will also be doubled
- As speed of light is directly proportional to distance it will also be doubled
