No, the relative refractive index between two media cannot be less than unity. The relative refractive index is defined as the ratio of the speed of light in a vacuum to the speed of light in the medium, and since the speed of light is always slower in a medium than in a vacuum, the relative refractive index is always greater than or equal to 1.

What is the value of absolute or relative refractive index?
The absolute refractive index is a measure of the speed of light in a medium compared to its speed in a vacuum, while the relative refractive index compares the speed of light between two different media. Both values help determine how light is bent or refracted as it passes through different materials.
What does relative refractive index tells?
The relative refractive index describes the change in speed of light as it moves from one medium to another, indicating how much the light bends or refracts at the interface of the two media. It is calculated as the ratio of the speed of light in a vacuum to the speed of light in the medium in question. The larger the relative refractive index, the more the light is bent or refracted as it enters the medium.
What is relative refractive index?
Relative refractive index is a unitless measure that compares the speed of light in a given medium to the speed of light in a vacuum. It is calculated by dividing the speed of light in a vacuum by the speed of light in the medium. This index helps determine how much a light ray will be bent or refracted as it passes from one medium to another.
What is refractive index of AIR?
1Ideally speaking, the ratio of the sines of the angles of incidence and refraction will be the same if the medium is the same. So the refractive index will be 1.However, refractive index is, again, a relative value. If we say that the refractive index of glass is 1.5, it implies that the refractive index of glass, with respect to air is 1.5. So the value might change based on the media involved in refraction.It can also be safely concluded, without much Physics, that any multiplicative quantity for the standard element will be 1. (ex: speed of sound is Mach 1)
What do you mean by refractive index and what are factor in which it depends?
Refractive index is a measure of how much light is bent, or refracted, when entering a material. It depends on factors such as the material's density, composition, and atomic structure, as well as the wavelength of the light passing through the material. A higher refractive index indicates a greater bending of light.
Can relative refractive index between 2 media be less than unity?
yes

What is relative index?
The ratio of speed of light in a given pair of media , gives us a measure of the extent of refraction of a ray of light as it goes from one medium to another. We use this ratio to define a term called the relative refractive index for a given pair of media . A relative refractive index is light that passes from one transparent medium to another.

What is the speed of light in media?
The answer depends on the refractive index of the media.

What happens when speed of light enters a new kind of medium?
When light passes from one medium to another with a different refractive index, andnot in a direction perpendicular to the boundary between the media, its speed changes.
When a light wave enters into a medium of different optical density?
When a light wave enters a medium of different optical density, its speed and direction may change due to the change in the medium's refractive index. This change in speed and direction results in phenomena like reflection, refraction, and dispersion of light waves.
In what direction does light turn when it refract?
that depends on the refractive index of the surface refracting the light beam. This is also affected by the light's wavelength and temperature of the media. Sage.
If the speed of light was the same in all materials would a lens cause light rays to bend?
No. Without refraction at a boundary between media with different refractive indices, lenses wouldn't work. The only way we would have of forming real images would be with curved mirrors.
