The speed of light in a vacuum is a universal scientific constant that is essential to the field of physics. What letter do we use to denote it?
Answer c
The speed of light, indicated by the symbol c, is equal to 299,792,458 meters per second, or approximately 300,000 kilometers per second or 186,000 miles per second. According to the special theory of relativity, c is the maximum speed at which matter, energy, and any information-carrying signals may travel through space.
