what is the formula for calculating the speed of light. The above formula is used for calculating the changes that occur when objects approach the speed of light. Average speed total distance total time Common units for speed are kilometers per hour kph miles per hour mph feet per second fts and meters per second ms.

The speed of light formula is c c nl where n is the light frequency and l is the wavelength. As such the formula is written as. The refractive index of a medium is calculated by the formula.
The formula looks like this.
The frequency f wavelength l and wave speed v are related by the equation. The formula defines the energy E of a particle in its rest frame as the product of mass m with the speed of light squared c 2Equivalently the mass of a particle at rest is equal to its energy E divided by the speed of light squared c 2Because the speed of light is a large number in everyday units approximately 3 10 8 meters per second the formula implies that a small amount of. Basically an object in motion undergoes 3 relativistic changes. Even if the vacuum is inside a box in a rocket traveling away from earth both an astronaut in the rocket and a hypothetical observer on earth will measure the speed of light moving through that box to be exactly c.
