Question
(I) The critical angle for a certain liquid-air surface is $47.7^{\circ} .$ What is the index of refraction of the liquid?
Step 1
7^{\circ}$. The critical angle is the angle of incidence beyond which rays of light passing through a denser medium to the surface of a less dense medium are no longer refracted but totally internally reflected. Show more…
