For a given spatial position and time, this quantity is the ratio between the magnitude of the electric field and the magnetic field for a wave. Maxwell discovered that the square of this quantity equals the reciprocal of the product of vacuum permittivity and permeability.

For a given spatial position and time, this quantity is the ratio between the magnitude of the electric field and the magnetic field for a wave. Maxwell discovered that the square of this quantity equals the reciprocal of the product of vacuum permittivity and permeability. The meter is defined using this value, which was found to be constant in any direction in the Michelson-Morley experiment. Index of refraction is the quotient of this value in a material and this value in a vacuum. The square of it is the proportionality constant in Einstein's mass-energy equivalence. For 10 points, name this constant equal to about 3.0 times ten to the eighth meters per second, symbolized c.
