The value of the speed of light
WebJan 13, 2024 · The Dutch scientist deduced the value of the speed of light to be 131,000 miles per second. However, the correct value is 186,000 miles per second. Time Of Flight … WebThe speed of light has a constant value of c in a vacuum. However, in a transparent material with a refractive index n > 1, the velocity of light in the material is reduced to c/n. Thus for a high-energy particle traveling at velocity v = βc, if β > 1/n, we can say that the particle is “traveling faster than light” in the material.
