Detailed Solution
Download Solution PDFThe correct answer is Water.
Key Points
- Refractive Index is the ratio of the light's speed in a vacuum to its speed in a specified medium.
- It is a dimensionless quantity.
- Formulae are given for the refractive index
- n = c/v
- n = refractive index
- c = velocity of light in a vacuum.
- v = velocity of light in a specified medium.
- From the given formulae we get, the Refractive index is the inverse relation to Light's speed.
- The refractive index of the material is high, then the light's speed will be low and vice-versa.
- In the given question, the refractive indices of Kerosene, Turpentine, and water are 1.44, 1.47 and 1.33, respectively.
- So, the water has the lowest refractive index among all so, the speed of light will be maximum in water.
- Turpentine has the highest refractive index, so the speed of light will be low in the Turpentine.
