Question

Does refractive index increases with the increase in angle of deviation?

Answer 1

Refractive Index $\left(\mu \right)$:

It is the measurement of the density of medium or optical density.

Relation between refractive index and angle of deviation.

$\mathrm{\mu }=\frac{\sin \left(\frac{{\mathrm{D}}_{\min }+\mathrm{A}}{2}\right)}{\sin \left(\frac{\mathrm{A}}{2}\right)}$

Where $\mathrm{D}$ is angle of deviation and $\mathrm{A}$ is angle of prism.

The angle of Deviation $\left(D\right)$:

1. It is the angle made by emergent ray with incident ray.
2. Experimentally it is found that if the refractive index of the material decreases, the angle of deviation also decreases and increases with an increase in refractive index.

So, we can say that yes refractive index increases with the increase in the angle of deviation.
