The speed of light is a universal constant denoted by c. In other words speed distancetime. The speed of light formula is c c nl where n is the light frequency and l is the wavelength.
The speed of light is a universal constant denoted by c.
Einsteins theory of special relativity tells us the speed of light is 186000 miles per second 300 million meters per second. Constant speed represents how fast something moves. The principle of the constancy of the speed of light. The constant speed formula is defined as the ratio of constant distance traveled divided by the amount of time taken to travel the respective distance.
