Question

What is the refractive index of a medium when the light strikes the medium after traveling through air at an angle of 23.3° and the refracted angle is 14.6°?

Answer 1

\(\dfrac{\eta_1}{\eta_2}=\dfrac{sin\theta_2}{sin\theta_1}; \eta\)= refractive index, \(\theta \) =angle

refraction index,\(\eta\), of air is 1.
