Question

Calculate the refractive index of a material, when angle of incidence in air is 50° and angle of refraction in the material is 36°.

Answer 1

\[ \mu = \frac{\sin i}{\sin r} \]

\[ = \frac{\sin 50^\circ}{\sin 36^\circ} \]

\[ = \frac{0.7660}{0.5878} \]

≈ 1.30

The refractive index of the material is approximately 1.30.
