23. What is the speed of light in glycerin (n = 1.47) expressed in terms of the speed of light in a vacuum ? (1) 2.040(B) 1.47c(C) 0.680 |

Answer» given, N=1.47 we KNOW that SPEED of light in vaccum=3×10^8m/s n= speed of light in VACUUM/ speed of light in glycerin1.47=3×10^8/speed of light in GLYCERIN 1.47/3×10^8=speed if light in glycerin147/3×100×10^8= speed if light in glycerin 49/100×10^8= speed of light in glycerin 0.49×10^-8m/s = speed of light in glycerin that's solve |
