What is relative refractive index formula?
When we measure speed of light in two different media, relative refractive index of medium 2 with respect to medium 1 is defined as the ratio of speed of light in medium 1 to speed of light in medium 2.
What are the units of relative refractive index?
Answer. The quantity Relative Refractive Index is Unit less i.e., it does not have any unit. This is ’cause Refractive Index is the ratio of speed of light within the material to the speed of light in vacuum. Therefore, its unit: (m/s)/(m/s) = Null.
What is the refractive index of vacuum and water?
The refractive index of water with respect to vacuum is 4/3 and refractive index of vacuum with respect to glass is 2/3.
What is the refractive index of glycerine?
1.46
How do you calculate the refractive index of water?
The speed of light is faster in water. The Refractive index of water is 1.3 and the refractive index of glass is 1.5. From the equation n = c/v, we know that the refractive index of a medium is inversely proportional to the velocity of light in that medium. Hence, light travels faster in water.
How do you solve refractive index Questions?
Question
- Refractive index of glass is 1.5. If the speed of light in vacuum is 3 X 108
- m/s, find velocity of light in medium.
- Solution: Refractive index, µ = C / v.
- = Velocity of light in vacuum / Velocity of light in medium.
- v = C / µ
- = 3 X 108 / 1.5.
- = 2 X 10 m/s. (Ans.)
- Speed of light in glass is 2 X 108 m/s.
