After Maxwell published his theory of electromagnetism, it became possible to calculate the speed of light indirectly by instead measuring the magnetic permeability and electric permittivity of free space. This was first done by Weber and Kohlrausch in 1857. In 1907 Rosa and Dorsey obtained 299,788 km/s in this way.
Speed is the magnitude of velocity. Velocity is the speed of an object plus its direction. Speed is called a scalar quantity and velocity is a vector quantity. Speed of Light. The fastest possible speed in the universe is the speed of light.r. s = d/t. 1  Instantaneous Speed-The speed of an object at a given moment. 2  The car may be travelling at 50 mph at this moment, but it may slow down or speed up during the next hour. 3  Average Speed-The average speed is calculated by the distance that an object traveled over a given interval of time.
