What is absolute refractive index? On what factors does it depend?
(N/A) Absolute refractive index: The refractive index of a medium with respect to vacuum (or in practice,air) is called its absolute refractive index.
$\therefore n = \frac{c}{v}$
Where $c$ is the speed of light in a vacuum and $v$ is the speed of light in the medium.
Dimensional formula of refractive index: $M^{0} L^{0} T^{0}$ (it is a dimensionless quantity).
The value of the refractive index of any medium depends on the following factors:
$1$. The nature of the medium.
$2$. The temperature of the medium.
$3$. The wavelength of the light used.

View SolutionThe $X-Y$ plane is taken as the boundary between two transparent media $M_{1}$ and $M_{2}$. $M_{1}$ in $Z \geq 0$ has a refractive index of $\sqrt{2}$ and $M_{2}$ with $Z < 0$ has a refractive index of $\sqrt{3}$. $A$ ray of light travelling in $M_{1}$ along the direction given by the vector $\overrightarrow{A} = 4\sqrt{3}\hat{i} - 3\sqrt{3}\hat{j} - 5\hat{k}$ is incident on the plane of separation. The value of the difference between the angle of incidence in $M_{1}$ and the angle of refraction in $M_{2}$ will be $....$ degrees.
