On what factors does the refractive index depend?
Factors affecting Refractive Index
The refractive index of a material is the measure of how much light bends or refracts as it passes through the material. The refractive index depends on several factors, which are explained below:
1. Density of the medium
The refractive index of a medium is directly proportional to its density. The denser the medium, the higher the refractive index.
2. Wavelength of light
The refractive index of a medium changes with the wavelength of light that passes through it. This phenomenon is known as dispersion. The refractive index of a medium is higher for shorter wavelengths of light.
3. Temperature
The refractive index of a medium changes with changes in temperature. As the temperature of the medium increases, the refractive index decreases.
4. Pressure
The refractive index of a medium changes with changes in pressure. As the pressure of the medium increases, the refractive index also increases.
5. Chemical composition
The refractive index of a medium depends on its chemical composition. Different materials have different refractive indices, even if they have the same density.
6. Optical activity
The refractive index of a medium can change if the medium is optically active. Optical activity is the ability of a material to rotate the plane of polarized light.
Conclusion
The refractive index of a medium is affected by various factors such as density, wavelength of light, temperature, pressure, chemical composition, and optical activity. Understanding these factors is important in various fields such as optics, chemistry, and materials science.

On what factors does the refractive index depend?
Here's your answer.. Refractive index of a medium depends upon the refractive index of the surroundings (when you consider the light ray passing from the surrounding into the medium), optical density, wavelength of the light and temperature.hope it helps;-)
