**Refractive Index**

The refractive index is a fundamental property of a material that describes how light propagates through it. It is defined as the ratio of the speed of light in a vacuum to the speed of light in the material.

**Refractive Index of Water Relative to Air**

Given that the refractive index of water relative to air is 1.33, it means that light travels 1.33 times slower in water than in air. This can be attributed to the difference in the density and molecular structure of water compared to air.

**Refractive Index of Oil Relative to Air**

Similarly, the refractive index of oil relative to air is 1.45. This means that light travels 1.45 times slower in oil than in air. The refractive index of oil can vary depending on the type and composition of the oil.

**Refractive Index of Oil Relative to Water**

To find the refractive index of oil relative to water, we can use the equation:

Refractive Index of Oil relative to Water = (Refractive Index of Oil relative to Air) / (Refractive Index of Water relative to Air)

Substituting the given values, we have:

Refractive Index of Oil relative to Water = 1.45 / 1.33 = 1.09

Therefore, the refractive index of oil relative to water is 1.09. This means that light travels 1.09 times slower in oil than in water.

**Refractive Index of Water Relative to Oil**

To find the refractive index of water relative to oil, we can use the reciprocal of the refractive index of oil relative to water:

Refractive Index of Water relative to Oil = 1 / (Refractive Index of Oil relative to Water)

Substituting the value we found earlier, we have:

Refractive Index of Water relative to Oil = 1 / 1.09 ≈ 0.92

Therefore, the refractive index of water relative to oil is approximately 0.92. This means that light travels 0.92 times slower in water than in oil.

**Summary**

- Refractive index of water relative to air: 1.33
- Refractive index of oil relative to air: 1.45
- Refractive index of oil relative to water: 1.09
- Refractive index of water relative to oil: 0.92

These values describe how light propagates through different materials and are important in understanding the behavior of light when it passes through interfaces between these substances.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same:Negative Refractive Index: One of the most fundamental phenomena in optics is refraction. When a beam of light crosses the interface between two different materials, its path is altered depending on the difference in the refractive indices of the materials. The greater the difference, the greater the refraction of the beam. For all known naturally occurring materials the refractive index assumes only positive values. But does this have to be the case?In 1967, Soviet physicist Victor Veselago hypothesized that a material with a negative refractive index could exist without violating any of the laws of physics.Veselago predicted that this remarkable material would exhibit a wide variety of new optical phenomena. However, until recently no one had found such a material and Veselago’s ideas had remained untested. Recently, meta-material samples are being tested for negative refractive index. But the experiments show significant losses and this could be an intrinsic property of negativeindex materials.Snell’s law is satisfied for the materials having a negative refractive index, but the direction of the refracted light ray is ‘mirror-imaged’ about the normal to the surface.There will be an interesting difference in image formation if a vessel is filled with “negative water” having refractive index – 1.33 instead of regular water having refractive index 1.33.Say, there is a fish in a vessel filled with negative water. The position of the fish is such that the observer cannot see it due to normal refraction since the refracted ray does not reach to his eye.But due to negative refraction, he will be able to see it since the refracted ray now reaches his eye.Q. A ray incident on normal glass and “negative glass” at an angle 60°. If the magnitude of angle of refraction in normal glass is 45° then, what will be the magnitude of angle of refraction in the “negative glass”?
