Study Notes
Refractive Index
- Refractive index is defined as the ratio of the speed of light in a vacuum to the speed of light in a given material.
- It is a measure of how much a material bends light.
Light Behavior in a Material with a Higher Refractive Index
- When light enters a material with a higher refractive index, it slows down and bends towards the normal.
- The amount of bending depends on the difference in refractive indices between the two materials.
Factors Affecting Refractive Index
- Refractive index of a material is affected by its density, temperature, and chemical composition.
- The refractive index of a material can also be affected by the wavelength of light.
Dispersion of Light through a Prism
- When light passes through a prism, it is split into different colors due to the different refractive indices of the material for different wavelengths of light.
- This is known as dispersion and is the principle behind the formation of a rainbow.
Wavelength Dependence of Refractive Index
- The refractive index of a material changes with different wavelengths of light.
- This is why different wavelengths of light are affected differently by the refractive index of a material.
- Shorter wavelengths are generally bent more than longer wavelengths.
