The index of refraction depends on the following factors:
1. **The speed of light in the material** - The index of refraction is defined as the ratio of the speed of light in a vacuum to the speed of light in the material. Thus, it directly depends on the speed of light in the material.
2. **The wavelength of light** - The index of refraction can vary with the wavelength of light due to dispersion, meaning that different wavelengths (colors) of light can refract at different angles as they pass through a material.
**Microscopic roughness** does not directly influence the index of refraction itself; instead, it may affect the scattering of light and the effective optical path but is not a factor that alters the fundamental value of the index of refraction.
In summary, the correct selections are:
- The speed of light in the material
- The wavelength of light
