Light travels with a velocity 1.5 x 108 m/s in a medium. On entering second medium its velocity becomes 0.75 x 108 m/s. What is the refractive index of the second medium with respect to the first medium? |

Answer» 10^8m/s be the VELOCITY of LIGHT in first medium (V1)and 0.75x10^8m/s be the velocity of light in second medium(V2)THEREFORE, 2n1=V1/V2=1.5x10^8/0.75x10^8=0.75/1.5=10/3Hence,the REFRACTIVE index of the second medium with respect to first medium is 10\3 |
