The correct answer is Refractive index . Key Points The refractive index of a medium is defined as the ratio of the speed of light in a vacuum to the speed of light in that medium. It is a dimensionless quantity and symbolized by "n". The mathematical formula for refractive index is n = c/v, where "c" is the speed of light in a vacuum, and "v" is the speed of light in the medium. The refractive index determines how much the path of light is bent or refracted when it enters a different medium. A higher refractive index indicates that light travels slower in the medium compared to a vacuum. The refractive index is a critical parameter in optics, influencing lenses, prisms, and optical instruments. Additional Information Frequency Frequency refers to the number of wave cycles that pass a given point per second. It is measured in hertz (Hz). It is a fundamental property of waves, including light waves, but it does not define the speed of light in a medium. The frequency of light remains constant when it enters a different medium, even though its speed and wavelength may change. Wavelength Wavelength is the distance between two successive crests or troughs of a wave. It is inversely proportional to the frequency of the wave and directly influenced by the speed of the wave in a medium. When light enters a medium, its wavelength changes, but the refractive index is determined by the speed, not the wavelength. Amplitude Amplitude refers to the maximum displacement of a wave from its equilibrium position. It is associated with the intensity or brightness of light but does not influence the refractive index of a medium. The refractive index depends solely on the speed of light in the medium and not on its amplitude.

Wavelength
Wavelength is the distance between two successive crests or troughs of a wave.
It is inversely proportional to the frequency of the wave and directly influenced by the speed of the wave in a medium.
When light enters a medium, its wavelength changes, but the refractive index is determined by the speed, not the wavelength.
Amplitude
Amplitude refers to the maximum displacement of a wave from its equilibrium position.
It is associated with the intensity or brightness of light but does not influence the refractive index of a medium.
The refractive index depends solely on the speed of light in the medium and not on its amplitude.
