The speed of light isn't represented by an equation; it is represented by the letter c. c figures in many applications in physics, so you would have to be more specific about what you are looking for.
c = 299,792,458 meters/second or c = 1/sqrt(μ0ε0)
Speed of light= c
c= E/f
The equation isv ≈ c
Energy equals mass times the speed of light squared. C is the speed of light
Speed of light in a material = c / (refractive index of the material) . ' c ' = speed of light in vacuum = 299,792,458 meters per second.
For example, if a star is at a distance of 5 light-years, it will take 5 years to travel there at the speed of light.
The equation is:c = 299,792,458 meters per second in vacuum .For any substance in general:c = (299,792,458 m/s) / (the refractive index of the substance)
E=mc2
The speed of light.
The equation isv ≈ c
The speed of light in a vacuum is 300,000 kilometers per second - you don't need an equation for that. Two equations that involve the speed of light are: 1) Speed = wavelength x frequency (this equation applies to any wave, not just light) 2) Snell's law, which relates the speed of light in different substances with the substance's index of refraction. The equation for the speed of light is: c = (299,792,458 meters per second) divided by (refractive index of the medium) The refractive index of vacuum is precisely 1 .
Energy equals mass times the speed of light squared. C is the speed of light
That equation is the equation that Albert Einstein came up with to describe how to calculate the speed of light. E = energy m = mass c = speed of light
The Equation is:c = K where'c' = the speed of light'K' = a constant = 299,792,458 meters/second
Partly to ensure that the dimensions of the equation balance.

E is a multiple of the speed of light, c is the speed of light, m is merely a mass.
Speed of light in a material = c / (refractive index of the material) . ' c ' = speed of light in vacuum = 299,792,458 meters per second.
For example, if a star is at a distance of 5 light-years, it will take 5 years to travel there at the speed of light.
