The speed of light in a transparent medi...

The speed of light in a transparent medium is `2.4xx10^(8)` m/s. Calculate absolute refractive index of the medium.

Text Solution

Verified by Experts

Given : `v_(1) =3xx10^(8)` m/s
…..[velocity of light in vacuum]
`v_(2)=2.4xx10^(8)` m/s
To find : `""_(1)n_(2)`
Formula : `""_(1)n_(2)=(v_(1))/(v_(2))`
Solution : `""_(1)n_(2)=(v_(1))/(v_(2))=(3x10^(8))/(2.4x10^(8))`
