how to find the speed of light in a diamond. Using the definition of n we can find the speed of light through lead. Strategy We can calculate the speed of light in a material v from the index of refraction n of the material using the equation n c v.
Once you know the index of refraction youve basically got your. Using the definition of n we can find the speed of light through lead. Speed of light in vacuum310⁸msec Given refractive index of Diamond n25 Let the speed of light in Diamond bexmsec.
Thats more than 10000 times the speed of the orbiting space shuttle.
N c v. 242cv so vc242 c3x108 msec so v124x108 msec. Once you know the index of refraction youve basically got your. The index of refraction is defined as the ratio of the sped of light in a vacuum to the speed of light in the meduiu of interest in the is case diamond.
