Question

define Refractive Index of a transparent medium the speed of light in a medium of absolute refractive index 1.5 is 2 x 10 ki power 8 m s -1 what is the speed of light in vacuum​

Answer 1

Answer:

speed of light = 3×10 ki power 8 m/s

Explanation:

refractive index formula = c/v

Given,refractive index=1.5

speed of light in medium(v) = 2×10 ki power 8

therefore,c= 1.5×2×10ki power 8 = 3 × 10ki power 8
