Can absolute refractive index exceed unity?
The absolute refractive index of a medium cannot exceed unity because speed of light is maximum in vacuum.
Can relative refractive index of a medium can be less than unity?
Can the relative refractive index of a medium w.r.t. another medium be less than unity? Yes, for example, the relative refraction index of water w.r.t. glass =4/33/2=89<1.
What is the possible value of absolute refractive index of a medium?

Absolute Refractive Index of a Medium – Definition The absolute refractive index is defined as the ratio of the speed of light in vacuum and in the given medium. The absolute refractive index should never be less than 1.
Is it possible for the refractive index of a medium to be less than 1?
Refractive indices less than 1 can occur and if the phase velocity of the light in the medium is faster than the speed of light. Negative refractive indices can occur if both the permittivity and permeability of the material are both negative at the same time.
Can the absolute refractive index value of a medium be less than one Why?
No, the absolute refractive index of a medium can not be less than one because the speed of light in any medium is always less than that in a vacuum.
What is difference between refractive index and absolute refractive index?
Physical Science Relative refractive index : Relative refractive index is the ratio of the speed of light in the medium 1 to the speed of light in medium 2. Absolute Refractive Index : Absolute refractive index is the ratio of the speed of light in vaccum to the speed of light in the medium.
Why the absolute ri of any medium cost be less than 1?
If the absolute refractive indices of water, benzene, and sapphire are 1. 33, 1. 77 respectively, then which medium has the maximum relative refractive index?
Why a medium can have absolute refractive index more than 1?
absolute refractive index can never be less than one . As absolute refractive index is ratio of speed of light in vacuum to that in the given medium, we can say it is alwaysgreater than one. This is because light travels with the highest speed in vacuum.
What is the difference between absolute refractive index of a medium and the relative refractive index of two mediums What is the relation between them?
Relative refractive index: When light travels from one medium to another medium, then the refractive index is known as the relative refractive index. Absolute refractive index: When light travels from vacuum to another medium, then the refractive index is known as the absolute refractive index.
Why is absolute refractive index is greater than 1?
The refractive index of a medium for a light of given wavelength is the ratio of the speed of light in vacuum to its speed in that medium. So, as we know that the maximum speed of light, is its speed in vacuum.so, the above ratio will be always greater than 1.
Why refractive index of a medium Cannot be less than 1?
Refractive index of a medium is always greater than 1 (it cannot be less than 1) because the speed of light in any medium is always less than that in vacuum.
