My answer is: it is the relationship between the angle of incidence and the angle of refraction.
Is it correct? If not, what should be the correct answer?

The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium.
The refractive index of a medium is a measure of how much the speed of light is reduced when it travels through that medium. It is defined as the ratio of the speed of light in a vacuum to the speed of light in the medium.
The refractive index of a medium is typically measured by shining a light beam through the medium and measuring the angle of refraction. This angle can then be used to calculate the refractive index using Snell's law.
The refractive index of a medium can be affected by various factors such as temperature, pressure, and the chemical composition of the medium. It can also vary depending on the wavelength of the light being used.
The refractive index of a medium is an important property in optics and is used to determine how light will behave when passing through different materials. It also plays a crucial role in the design and functionality of optical instruments such as lenses and prisms.
Some common examples of mediums with high refractive indices include diamond, water, and glass. Air, on the other hand, has a low refractive index compared to these materials.
